What is a 5MB WAV file useful for?
A 5 MB WAV at 44.1 kHz 16-bit stereo provides approximately 30 seconds of uncompressed audio — the standard duration for sound effect libraries, audio samples, and short vocal recordings. Use it to test audio transcoding throughput (WAV-to-MP3 or WAV-to-AAC), to verify that your digital audio workstation (DAW) integration correctly handles the RIFF chunk structure, and to benchmark Python audio libraries on a realistic file size.
What's inside this file?
Generated by ffmpeg. A 440 Hz sine tone approximately 30 seconds long at 44.1 kHz, 16-bit PCM, stereo. The data chunk contains approximately 2,646,000 stereo samples. At 176,400 bytes/sec, 30 seconds of stereo 16-bit 44.1 kHz audio requires exactly 5,292,000 bytes — the remaining space to the 5 MB target is taken by the WAV RIFF/fmt/data chunk headers (44 bytes).
