Utilities
Once you have imported a sound wave, you can export it to memory or a file in one of the supported formats: OGG VORBIS, WAV, BINK, RAW (PCM).
Note: Exporting to BINK format is only supported on Windows x64, Mac, and Linux.
You can transcode one RAW format into another using the corresponding functions.
To obtain basic audio header information (metadata) from audio data, consider using the following functions as they are more cost-effective than the full process of importing the audio into a sound wave.
To manually determine the audio data format, you have two options. The first is based on file extension recognition, while the second method involves analyzing the audio data, which is more accurate but requires loading the audio data into memory. Note that the process is automatically performed during the import stage, so manual intervention is not necessary.
You can use the OnGeneratePCMData delegate to obtain PCM data as the sound wave plays. This is useful when processing or analyzing the PCM audio data.
The OnPopulateAudioData delegate can be used to obtain newly populated PCM data, which is particularly useful for streaming sound waves and can simplify the audio analysis process.
You can scan a directory, with the option to search recursively, for audio files. The resulting string array will contain the paths of the audio files, which can be imported.
This function can convert seconds (e.g., playback time) into either the hh:mm:ss or mm:ss format string, depending on the length.
