Frequently Asked Questions

Why would I need 1 hour of silence?

Common uses: testing audio player memory usage over long playback, silent background 'audio' to keep Bluetooth headphones connected, sleep timer functionality testing, and placeholder audio in automated video rendering.

Should I use MP3 or WAV for 1 hour?

Use the 54.93 MB MP3 when transfer size matters. Use the 606 MB WAV when the test specifically requires uncompressed PCM. They encode silence differently and should not be described as identical artifacts.
