SoX VS Lossless Audio Checker

To get the WAV file, some of the ways are using sox and running the command sox -e signed-integer -b 16 -r 16k -c 1 out.raw out.wav, or writing a python script using the wave library. Source: 11 months ago

Also sox can be handy for just audio. You can't beat ffmpeg in general, finding the right command options and testing can take time but with any of them it's worth building up your toolkit. Source: 12 months ago

SoX is great for 99% of command-line audio work. The documentation can be tough to follow (and sometimes just missing or wrong), but once you wrap your head around the syntax and chaining effects together it is impressive what you can do. Source: over 1 year ago

For no good reason, this prompted me to attempt to write a function in Bash which takes advantage of SoX to snap recorded audio to a desired length by speeding up or slowing down as needed. Source: over 1 year ago

Yeah, sure. I use Lossless Audio Checker, which is single threaded but seems to generate fewer false negatives. That is to say it's slow, but doesn't flag genuine lossless files as probable mpegs as much. My biggest beef with LAC is how annoying it is about its log files. It doesn't save them in the folder with the FLACs so I have to manually copy every log file from my Documents folder to the proper location.... Source: about 1 year ago

You can use this to check for artificially inflated bitrate/bitdepth, its fairly accurate, or fbits which can detect exactly how much of the bitdepth is being used. Source: almost 2 years ago

If you have Windows, the Lossless Audio Checker can tell you in about 2 seconds if a WAV or FLAC file has been upsampled/ upscaled/ transcoded. There is also a CLI version for Mac. Source: over 2 years ago

Losslessaudiochecker.com paired with spek.cc when in doubt gets the job done. Source: over 2 years ago

I read about it about a year ago and recently did some tests using https://losslessaudiochecker.com/ to see for myself. And indeed, some songs 320 or FLAC audio files I sourced from deezer were upscaled. Source: over 2 years ago
