Audio WAV Example Files For QA Manual Testing WAV files: a 1 second clip (16 KB) and a 5 second clip (80 KB), both a 440 Hz tone. WAV is uncompressed, so the size grows in a straight line with duration, and the 5 second file is exactly five times the 1 second file plus the header. That makes it handy for checking size limits and upload progress. WAV is also what many speech and audio tools expect as input. The files are still small enough to commit to a repository, and they test a very different code path from compressed formats like MP3.
