wav is a binary file format generally used for storing audio data.
Format
See Wikipedia, www-mmsp.ece.mcgill.ca or one of many other resources for a file format overview.
Properties
- The maximum file size is limited to 4GB (uint32_t used for the file size header field). However, many applications routinely ignore this field, and just load however many samples are in the file.
- While sigrok stores the analog values in a WAV file as they are, many audio applications that process WAV files cannot deal with sample values outside the range -1 to +1. Thus when generating a WAV file with sigrok with a view to using an audio application on that file, it is recommended to scale down the values to within the audio range.
