Firefox supports 8-bit and 16-bit PCM only ( https://support.mozilla.org/en-US/kb/html5-audio-and-video-firefox#w_open-media https://support.mozilla.org/en-US/kb/html5-audio-and-video-f... ). I don't know why, exactly.
- londons_explore 7y agoThats silly... 16 bit audio really doesn't have enough dynamic range for many uses now. Listen to a bit of classical music with very loud and very quiet bits and you'll hear quantization hiss in the quiet bits. 16 bits allows a dynamic range of 96dB while sounds you might come across in everyday life can peak over 130dB briefly.

- bildung 7y agoWhile the actual analog sounds may indeed have a higher signal to noise ratio than 96db, most ADCs haven't, i.e. for most digital recordings 16bit should be more than enough.
- jbay808 7y agoSince audio is usually sampled around 44 kHz, which is slow by signal processing standards, most ADCs can exceed 16 bits by supersampling and averaging the results.
