>But that's referring to privacy.resistFingerprinting (RFP), not adding randomness having a randomized fingerprint is a fingerprint value in and of itself. That may leak more entropy bits if you have a fairly common hardware configuration Also, regarding webaudio fingerprinting, afaik it's not a real threat. https://github.com/WebAudio/web-audio-api/pull/2224#discussi... https://github.com/w3cping/tracking-issues/issues/53#issueco... >As I said, I can't use RFP, it breaks too many sites. Weird. I only know a few sites that break with RFP on, and I don't use them frequently.

Fun fact, I ran into the esampling problem myself back in April when I posted https://github.com/WebAudio/web-audio-api/issues/30, V2 of the spec will allow this natively, but it also not seemingly making any headway towards initial release so who knows when it'll land... What you can do though is look at the first few bytes of an .mp3 file (since it's a file drop/file load) to just directly read the sample rate from the MP3 block header[1], where you directly check the value encoded by [data[19], data[20]]: if it's [0,0] that means it's 44100, [0,1] means it's 48000, [1,0] means it's 32000 and that's it. There are no other sample rates allowed for MP3. [1] http://mpgedit.org/mpgedit/mpeg_format/MP3Format.html for the full block format)

hi HN! I've been working in the browser audio domain recently and noticed to my surprise that WebAudio has no way to decode audio files efficiently. WebAudio has no support for partial decoding and can only decode entire audio files upfront which results in huge CPU and memory usage. For example, decoding a typical stereo 44.1 KHz 1-hour long audio file (e.g a podcast) into uncompressed floating point samples would consume (3600s * 44100Hz * 4 bytes * 2 channels) = ~1.27 GB of memory. Nice Obviously this isn't acceptable so I ended up creating this library to work around this issue. I ported FFmpeg over to WASM using Emscripten (a painful process) and then implemented an audio decoder with support for partial decoding. I hope this library can help anyone else with the same issue or at least serve as an additional reference for those look
