Using Audiowrite is clipping WAV files (2024)

Sound file formats such as wav are not data files. They are not intended to represent specific signal levels, and make not attempt to deal with very common issues such as Mic Level (about 1 millivolt) or Line Level (about sqrt(3) volts for pro, about 1/2 V for consumer), let alone pre-amp speaker levels or post-amp driving speakers. They are not Pa readings. Sound file formats store information about signal levels relative to the maximum of the system. The signal information dealt with stays the same regardless of whether someone has their volume set at half or if they have turned it up to 11.

The way to do this without clipping is to not use a sound file.
