<h3>Welcome</h3>
<p>The Audio System Design Tool++ lets you easily draw a system to process 16 bit, 44.1 kHz streaming audio while your Arduino sketch also runs.</p>
<p>Export will generate code to copy into the Arduino editor, to implement your system.</p>
<p>Most objects provide simple functions you can call from setup() or loop() to control your audio project!</p>
<h3>Tool++ extra functionality</h3>
<p>Class export that allows the design to be seperated into different objects which can be linked together in a "main" design</p>
<p>Experimental live edit of the design using OSC<br>

</p>
<p>UI objects that can control the project live</p>
<p>More Info about the new functionality here:<br>

    <a href="https://github.com/manicken/manicken.github.io" target=\"_blank\">Github</a>
</p>
<h3>Offline Use</h3>
<p>This tool does not use a server.  A stand-alone copy is provided with the Teensy Audio Library, in the gui folder.</p>
<p>But to make it much easier there is either<br>
    <a href="https://github.com/manicken/arduinoAPIwebserver" target=\"_blank\">Arduino IDE - API webserver</a> or <br>
    <a href="https://github.com/manicken/vscode_api_webserver" target=\"_blank\">VSCODE - API webserver</a> <br>
    that can be used together with the tool.<br>
    Those webservers make it possible to push the export direct to either IDE,<br>and thus either copy/paste or export to zip is required.
</p>

	<div class=tooltipinfo>
    <p>The ultimate mixer.</p>
    <p>To use this, normally you don't have to do anything<br>
        as the Tool Autogenerates code for all mixer size-variants you use.<br>
    </p>
        
	<p>Combine up to n audio signals together, each with adjustable gain.<br>
		All channels support signal attenuation or amplification.</p>
    <p>note. the maximum amount of inputs a AudioStream object can have is 255, this then the case for this mixer as well.</p>
	<p>	When used together with<br> a <b>array type</b> source,<br>(a object with the array declaration ['arraysize'] after the name)<br>
	    then it should be set to only one input,<br>the code generator will make a mixer matching the arraysize.<br><br>

		<tr class=odd><td align=center>In n</td><td>Input signals</td></tr>
		<tr class=odd><td align=center>Out 0</td><td>Sum of all inputs</td></tr>

	<h3>Functions</h3>
	<p class=func><span class=keyword>gain</span>(channel, level);</p>
	<p class=desc>Adjust the amplification or attenuation.  "channel" must
		be 0 to n.  "level" may be any floating point number from 0 to 32767.0.
		1.0 passes the signal through directly.  Level of 0 shuts the channel
		off completely.  Between 0 to 1.0 attenuates the signal, and above
		1.0 amplifies it.  Negative numbers may also be used, to invert the
		signal.  All n channels have separate gain settings.
	</p>
	<p class=func><span class=keyword>gain</span>(level);</p>
	<p class=desc>Adjust the amplification or attenuation for all channels.
		"level" may be any floating point number from 0 to 32767.0.
		1.0 passes the signal through directly.  Level of 0 shuts the channel
		off completely.  Between 0 to 1.0 attenuates the signal, and above
		1.0 amplifies it.  Negative numbers may also be used, to invert the
		signal. 
	</p>
    <p> If you prefer and still use the C++ template mixer<br>
        you can use the C++ template mixer code provided by the theMixer.h object in the mixer category<br>
        to use the template mixer structure you also have to enable a setting<br>
        @ settings-Arduino-"other settings"-"Use C++ Template Mixer (obsolete)"</p>

	</p>
	<p class=desc><i>noiseshaping</i>: noise shaping is applied at the aforementioned transition if true (default: true)
	</p>
	<p class=desc><i>attenuation</i>: target attenuation of the anti-aliasing filter (default: 100dB). The attenuation is not reached if a filter longer than 161 is needed.
	</p>
	<p class=desc><i>minHalfFilterLength</i>: half of the guaranteed resampling filter (internally restricted to 80, default: 20). The filter might be longer if needed to achieve the requested attenuation.
	</p>
	<p class=desc><i>maxHalfFilterLength</i>: Restricts the maximum length of the resampling filter. The maximum half filter length is 80. This parameter can be used to further restrict the length in order to limit the processor usage.
	</p>
	<p>The windowed (Kaiser window) sinc-function is used as resample filter (i.e. to interpolate the incoming signal). The longer the filter, the better the quality of the resampled signal. However, a longer filter has a higher group delay and increases the processor usage. The sinc- filter also serves as anti-aliasing filter if the input sample rate is larger than 44.1kHz. The filter length is automatically increased at high input sample rates to reach the specified attenuation. However its half length is restricted to 80. 32bit floating point arithmetic is used at the resampling stage and the resampled signal is transformed to 16 bit integers afterwards. Here it is possible to apply triangular shaped dither and noise shaping to increase the perceived signal-to-noise-ratio.</p>

	<p>Only 16 bit PCM, 44100 Hz WAV files are supported.  When mono
		files are played, both output ports transmit a copy of the
		single sound.  Of course, stereo WAV files play with the left
		channel on port 0 and the right channel on port 1.
	</p>
	<p>A brief delay after calling play() will usually occur before
		isPlaying() returns true and positionMillis() returns valid
		time offset.  WAV files have a header at the beginning of the
		file, which the audio library must read and parse before
		playing can begin.
	</p>
	<p>While playing, the audio library accesses the SD card automatically.
		If card access is required, you must
		<a href="http://www.pjrc.com/teensy/td_libs_AudioProcessorUsage.html" target="_blank">use AudioNoInterrupts()</a>
		to prevent the library from accessing the SD card while you use it.
		Disabling the audio library interrupt for too long may cause audible
		dropouts or glitches.
	</p>
	<p>An experimental SD library optimization exists, which can remove these
		SD library restrictions.  It also allows reliable playback of more
		files at the same time.  To enable this special code, find and edit
		the SD_t3.h file within your Arduino folder.  See the comments within
		that file for details.

<h3>Summary</h3>
	<div class=tooltipinfo>
	<p>The chorus effect simulates the richness of several nearly-identical

	the same but at a slightly different point in time. This is a type of
	comb filtering.</p>
	</div>
	<p>Chorus combines one or more samples ranging from the most recent
	sample back to about 50ms ago. The additional samples are evenly spread
	through the supplied delay line, and there is no modulation.</p>
	<p>If the number of voices is specified as 2, then the
	effect combines the current sample and the oldest sample (the last one
	in the delay line). If the number of voices is 3 then the effect combines
	the most recent sample, the oldest sample and the sample in the middle of
	the delay line.</p>
	<p>For two voices the effect can be represented as:<br/>
	result = (sample(0) + sample(dt))/2<br/>
	where sample(0) represents the current sample and sample(dt)
	is the sample in the delay line from dt milliseconds ago.</p>

<script type="text/html" data-help-name="AudioEffectFlange">
<h3>Summary</h3>
	<div class=tooltipinfo>
	<p>Originally, flanging was produced by playing the same signal on two synchronized
	reel-to-reel tape recorders and making one of the reels slow down and speed up by
	pressing on the flange of the reel (hence the name). This is a type of
	comb filtering, and produces a harmonically-related series of peaks and notches
	in the audio spectrum.</p>
	</div>
	<p>This flanger uses a delay line, combining the original voice with only one sample from the delay
	line, but the position of that sample varies sinusoidally.</p>
	<p>The effect can be represented as:<br>
	result = sample(0) + sample(dt + depth*sin(2*PI*Fe))</p>
	<p>The value of the sine function is always a number from -1 to +1 and
	so the result of depth*(sin(Fe)) is always a number from -depth to +depth.
	Thus, the delayed sample will be selected from the range (dt-depth) to
	(dt+depth). This selection will vary at whatever rate is specified as the
	frequency of the effect, Fe. Typically a low frequency (a few Hertz) is used.

	<h3>Functions</h3>
	<p class=func><span class=keyword>begin</span>(array, length);</p>
	<p class=desc>Initialize the filter.  The array must be 16 bit integers (the

	</p>
	<h3>Examples</h3>
	<p class=exam>File &gt; Examples &gt; Audio &gt; Effects &gt; Filter_FIR
	</p>
	<h3>Known Issues</h3>
	<p>Your filter's impulse response array must have an even length.  If you have
		add odd number of taps, you must add an extra zero to increase the length
		to an even number.
	</p>
	<p>The minimum number of taps is 4.  If you use less, add extra zeros to increase
		the length to 4.
	</p>
	<p>The impulse response must be given in reverse order.  Many filters have
		symetrical impluse response, making this a non-issue.  If your filter has
		a non-symetrical response, make sure the data is in reverse time order.
	</p>
	<h3>Notes</h3>
	<p>FIR filters requires more CPU time than Biquad (IIR), but they can
		implement filters with better phase response.
	</p>
	<p>A 100 point filter requires 9% CPU time on Teensy 3.1.  The maximum
		supported filter length is 200 points.
	</p>
	<p>The free
		<a href="http://t-filter.engineerjs.com/" target="_blank"> TFilter Design Tool</a>
		can be used to create the impulse response array.  Be sure to set the sampling
		frequency to 44117 HZ (it defaults to only 2000 Hz) and the output type to "int" (16 bit).
	</p>
	<p>
		If you use TFilter Design's "C/C++ array" option, it's output has "int" definition, which
		is 32 bits on Teensy 3.1.  Edit "int" to "short" for an array of 16 bit numbers,
		and add "const" to avoid consuming extra RAM.

	<h3>Notes</h3>
	<p>The <a href="http://recherche.ircam.fr/equipes/pcm/cheveign/pss/2002_JASA_YIN.pdf">YIN algorithm</a> (PDF)
		is used to detect frequencies, with many optimizations for
		frequencies between 29-400Hz.  This algorithm can be somewhat
		memory and processor hungry but will allow you to detect with
		fairly good accuracy the fundamental frequencies from
		electric guitars and basses.</p>
	<p>Within the code, AUDIO_GUITARTUNER_BLOCKS
		may be edited to control low frequency range.  The default
		(24) allows measurement down to 29.14 Hz, or B(flat)0.</p>
	<p>TODO: The usable upper range of this object is not well known.
		Duff says "it should be good up to 1000Hz", but may have trouble
		at 4 kHz.  Please <a href="https://forum.pjrc.com/threads/32252-Different-Range-FFT-Algorithm/page2">post feedback here</a>, ideally with audio clips for the NoteFrequency example.</p>
	<p>This object was contributed by Collin Duffy from his

	<h3>Audio Connections</h3>
	<p>This object has no audio inputs or outputs.  Separate i2s objects
		are used to send and receive audio data.  I2S master mode objects
		must be used, because this object configures the SGTL5000 in slave

		This object controls
		how the SGTL5000 will use those I2S audio streams.</p>

	<h3>Functions</h3>
	<p>These are the most commonly used SGTL5000 functions.</p>
	<p class=func><span class=keyword>enable</span>();</p>
	<p class=desc>Start the SGTL5000.  This function should be called first.
	</p>
	<p class=func><span class=keyword>volume</span>(level);</p>
	<p class=desc>Set the headphone volume level.  Range is 0 to 1.0, but

	<h3>Signal Conditioning</h3>

	<p>Usually these digital signal conditioning features should be left at their
		default settings.
	</p>

	<p class=func><span class=keyword>adcHighPassFilterFreeze</span>();</p>
	<p class=desc>By default, the analog input (either line-level inputs or mic)
		is high-pass filtered, to remove any DC component.  This function
		freezes the filter, so the current DC component is still substracted, but
		the filter stops tracking any DC or low frequency changes.
	</p>
	<p class=func><span class=keyword>adcHighPassFilterDisable</span>();</p>
	<p class=desc>Completely disable the analog input filter.  DC and sub-audible
		low frequencies are allowed to enter the digital signal.  This
		<a href="http://openaudio.blogspot.com/2017/03/teensy-audio-board-self-noise.html">may
		reduce noise</a> in some cases.
	</p>
	<p class=func><span class=keyword>adcHighPassFilterEnable</span>();</p>
	<p class=desc>Turn the DC-blocking filter back on, if disabled, or
		allows it to resume tracking DC and low frequency changes, if
		previously frozen. This is the default setting.
	</p>
	<p class=func><span class=keyword>dacVolume</span>(both);</p>
	<p class=desc>Normally output volume should be used with volume(), which
		changes the analog gain in the headphone amplifier.  This function
		on the other hand controls digital attenuation before conversion to analog, which
		reduces resolution, but allows another fine control of output
		signal level.  The ranges is 0 to 1.0, with the default (no digital attenuation)
		at 1.0.
	</p>
	<p  class=desc>dacVolume uses zero-crossing detect to avoid clicks, and graceful
		ramping is handled by the chip so that a new volume may be set directly in
		a single call.
	</p>
	<p class=func><span class=keyword>dacVolume</span>(left, right);</p>
	<p class=desc>Adjust the digital output volume separately on left and
		right channels.
	</p>
	<p class=func><span class=keyword>dacVolumeRamp</span>();</p>
	<p class=desc>Enable graceful volume ramping.  The dacVolume adjusts gradually using
		an exponential curve.  Pops or loud clicks are avoided when making large
		changes in volume level.
	</p>
	<p class=func><span class=keyword>dacVolumeRampLinear</span>();</p>
	<p class=desc>Enable faster volume ramping.  A slight click may be heard during a
		large volume change.
	</p>
	<p class=func><span class=keyword>dacVolumeRampDisable</span>();</p>
	<p class=desc>Do not use any gradual ramping.  The zero cross feature still helps
		for small changes, but large volume changes may produce a pop or click.
	</p>

	<h3>Audio Processor</h3>

	<p>The optional digital audio processor is capable of implementing
		one or more of: automatic volume control, surround sound control,
		bass enhancement, and tonal adjustments (either a
		simple tone control, or a parametric equalizer, or a graphic equalizer),
		in that order.
	</p>
	<p>These signal processing features are implemented in the SGTL5000 chip,
		so they do not consume CPU time on Teensy. However, the order of
		these processes is fixed in the hardware.
	</p>
	<p>It is good practice to mute the outputs before enabling or disabling
	the Audio Processor, to avoid clicks or thumps.
	</p>

	<p class=func><span class=keyword>audioPreProcessorEnable</span>();</p>
	<p class=desc>Enable the audio processor to pre-process the input
		(from either line-level inputs or microphone) before it's sent
		to Teensy by I2S.
	</p>
	<p class=func><span class=keyword>audioPostProcessorEnable</span>();</p>
	<p class=desc>Enable the audio processor to post-process Teensy's
		I2S output before it's turned into analog signals for the
		headphones and/or line level outputs.
	</p>
	<p class=func><span class=keyword>audioProcessorDisable</span>();</p>
	<p class=desc>Disable the audio processor.
	</p>
	<p class=func><span class=keyword>autoVolumeControl</span>(maxGain, response, hardLimit, threshold, attack, decay);</p>
	<p class=desc>Configures the auto volume control, which is implemented as a compressor/expander
	or hard limiter. 	<em>maxGain</em> is the maximum gain that can be applied for expanding, and
	can take one of three values: 0 (0dB), 1 (6.0dB) and 2 (12dB). Values greater than 2 are treated
	as 2. <em>response</em> controls the integration time for the compressor and can take
	four values: 0 (0ms), 1 (25ms), 2 (50ms) or 3 (100ms). Larger values average the volume
	over a longer time, allowing short-term peaks through.
	</p>
	<p class=desc>If <em>hardLimit</em> is 0, a 'soft
	knee' compressor is used to progressively compress louder values which are near to or above the
	threashold (the louder they are, the greater the compression). If it is 1, a hard compressor
	is used (all values above the threashold are the same loudness). The <em>threashold</em> is specified
	as a float in the range 0dBFS to -96dBFS, where -18dBFS is a typical value.
	<em>attack</em> is a float controlling the rate of decrease in gain when the signal is over
	threashold, in dB/s. <em>decay</em> controls how fast gain is restored once the level
	drops below threashold, again in dB/s. It is typically set to a longer value than attack.
	</p>
	<p class=func><span class=keyword>autoVolumeEnable</span>();</p>
	<p class=desc>Enables auto volume control, using the previously specified settings.
	</p>
	<p class=func><span class=keyword>autoVolumeDisable</span>();</p>
	<p class=desc>Disables auto volume control.
	</p>

	<p class=func><span class=keyword>surroundSoundEnable</span>();</p>
	<p class=desc>Enable virtual surround processing, to give a broader and
	deeper stereo image (even with mono input).
	</p>

	<p class=desc>Disable virtual surround processing. Before disabling, ramp up
	the width to maximum to avoid pops.
	</p>
	<p class=func><span class=keyword>surroundSound</span>(width);</p>
	<p class=desc>Configures virtual surround width from 0 (mono) to 7 (widest).
	</p>
	<p class=func><span class=keyword>surroundSound</span>(width, select);</p>
	<p class=desc>Configures virtual surround width from 0 (mono) to 7 (widest).
	<em>select</em> may be set to 1 (disable), 2 (mono input) or 3 (stereo input).
	</p>

	<p class=func><span class=keyword>enhanceBassEnable</span>();</p>
	<p class=desc>Enable bass enhancement. A mono, low-pass filtered copy of
	the original stereo signal has bass levels boosted and is then mixed back into
	the stereo signal, which is then optionally high pass filtered (to remove
	inaudible subsonic frequencies).
	</p>
	<p class=func><span class=keyword>enhanceBassDisable</span>();</p>
	<p class=desc>Disable bass enhancement. Before disabling, ramp down the bass
	enhancement level to zero.
	</p>
	<p class=func><span class=keyword>enhanceBass</span>(lr_lev, bass_lev);</p>
	<p class=desc>Configures the bass enhancement by setting the levels of the
	original stereo signal and the bass-enhanced mono level which will be mixed together.
	There is no high-pass filter.
	</p>
	<p  class=desc>When changing bass level, call this function repeatedly to ramp up or down the bass in
	steps of 0.5dB, to avoid pops.
	</p>
	<p class=func><span class=keyword>enhanceBass</span>(lr_lev, bass_lev, hpf_bypass, cutoff);</p>
	<p class=desc>Configures the bass enhancement by setting the levels of the
	original stereo signal and the bass-enhanced mono level which will be mixed together.
	The high-pass filter may be enabled (0) or bypassed (1). The cutoff frequency is specified
	as follows:

	<p class=func><span class=keyword>eqBands</span>(bass, treble);</p>
	<p class=desc>Configures bass and treble tone controls, which are

	<h3>Functions</h3>
	<p class=func><span class=keyword>play</span>(filename | File);</p>
	<p class=desc>Begin playing a WAV file.  If a file is already playing,
		it is stopped and this file starts playing from the beginning. The file to
		play may be given by either a character string or an open File object.
	</p>

	<p class=desc>Begin playing a WAV file.  If a file is already playing,
		it is stopped and this file starts playing from the beginning. If
		paused is true then the playing does not start immediately, but
		can be started and stopped with the pause function.
	</p>
	<p class=func><span class=keyword>pause</span>(bool);</p>
	<p class=desc>Pause or resume playing.  If not playing, this function has no effect. Resumes

	</p>
	<p class=func><span class=keyword>stop</span>();</p>
	<p class=desc>Stop playing.  If not playing or paused, this function has no effect.
	</p>
	<p class=func><span class=keyword>isPlaying</span>();</p>
	<p class=desc>Return true (non-zero) if playing, or false (zero)
		when stopped or paused.

	<p class=func><span class=keyword>isStopped</span>();</p>
	<p class=desc>Return true (non-zero) if stopped, or false (zero)
		when playing or paused.  
	</p>
	<p class=func><span class=keyword>isPaused</span>();</p>
	<p class=desc>Return true (non-zero) if paused, or false (zero)
		when playing or stopped.  
	</p>
	<p class=func><span class=keyword>positionMillis</span>();</p>
	<p class=desc>While playing, return the current time offset, in
		milliseconds.  When not playing, the return from this function
		is undefined.
	</p>
	<p class=func><span class=keyword>lengthMillis</span>();</p>
	<p class=desc>Return the total length of the current sound clip,
		in milliseconds.  When not playing, the return from this function
		is undefined.
	</p>
	<p class=func>static <span class=keyword>addMemoryForRead</span>(mult);</p>
	<p class=desc>Causes extra buffer memory for pre-loading SD card data
	to be allocated when play() is called, thus reducing the frequency of SD card accesses. 
	mult=2 will double the allocated memory, and so on.
	</p>
	<p class=func>static <span class=keyword>enableEventReading</span>(bool);</p>
	<p class=desc>Defaults to false, in which case SD card reads occur within
	the (interrupt-driven) audio update loop. If set to true then the EventResponder
	library is used to trigger SD card reads within the foreground code: this requires
	that loop() exits, or one of yield() or delay() are called within an infinite loop().
	
	Event reads generally allow more simultaneous WAV files to be played. This function may
	be called while one or more files are playing. [DISCLAIMER] there may be audio glitches and/or a loss
	of synchronisation as a result.
	</p>
	<h3>Examples</h3>
	<p class=exam>File &gt; Examples &gt; Audio &gt; WavFilePlayerI2S
	</p>
	<h3>Notes</h3>
	<p>Only 8- or 16-bit PCM WAV files are supported. 
		The bit rate of the file must match the configured AUDIO_SAMPLE_RATE.
		WAV files with from 1 to 8 channels are supported, 
		with outputs assigned starting from channel 0.
		Thus stereo WAV files play with the left
		channel on port 0 and the right channel on port 1.
	</p>
	<p>The player attempts to interleave the SD card reads such that simultaneous playback
	of multiple WAV files does not result in intermittent heavy load on the card, with
	long idle periods. With enableEventReading set to true, it is easily possible to play 16
	mono 44kHz 16-bit WAV files at once. Multi-track WAV files also reduce the CPU / SD card load,
	though they are obviously less flexible.
	</p>
	<p>No delay after calling play() is required before
		isPlaying() returns a valid value, and positionMillis() returns a valid
		time offset. 
	</p>
	<p>While playing, the audio library accesses the SD card automatically.
		If card access is also required for other purposes, you must
		<a href="http://www.pjrc.com/teensy/td_libs_AudioProcessorUsage.html" target="_blank">use AudioNoInterrupts()</a>
		to prevent the library from accessing the SD card while you use it.
		Disabling the audio library interrupt for too long may cause audible
		dropouts or glitches.
	</p>
	<p>An experimental SD library optimization exists, which can remove these
		SD library restrictions.  It also allows reliable playback of more
		files at the same time.  To enable this special code, find and edit
		the SD_t3.h file within your Arduino folder.  See the comments within
		that file for details. [Is this true?]
