I am trying to differentiate between multiple wav files using acoustic fingerprinting. I am using Chromaprint from AcoustID. I am using 32 bit windows. I have downloaded the file fpcalc.exe and am trying to run it on multiple wav files. The problem is, it is generating blank FINGERPRINT for those wav files. I am running the command

fpcalc.exe -raw <FILENAME>.wav

The files are in wav format and the size of the files is 1 SEC. I am running the same command on bigger files, then the FINGERPRINT is working fine.

Any pointers?

The Chromaprint library only works for larger files, I think the files should have at least 10 seconds to fingerprint.

Maybe you should look for alternatives like Python and Ruby who have libraries to fingerprint small audio files (if you search a bit).

You can use the gem that I made for wav files:

  • Thanks :) . Lukas explained it to me in this post.. https://groups.google.com/forum/#!topic/acoustid/Wo5zisCxU8Y – Abhishek Feb 24 '14 at 13:19
  • @Abhishek I'm looking for an answer too, if you find one that fits our needs to fingerprint small files, send me an email and let's work together. – Rafael Fragoso Feb 24 '14 at 22:27
  • @Rafel Actually for that small files.. I used md5hash or similar hashing algo to compare two files. I had only requirement that two small audio files should be same. I did not look it up any further on fingerprinting. – Abhishek Feb 25 '14 at 04:44
  • @Abhishek That's a smart answer for your problem. My problem is a little bit more complex, I'm trying to make my computer execute commands with my voice. I already have a prototype using one of the Google's services with voice recognition. But the problem is that I'm afraid to depend on Google. I'm pretty sure they'll add limits and billing in the future, so I kinda need to learn fingerprint and build my own API. – Rafael Fragoso Feb 25 '14 at 12:40
  • Thats cool. You can start a project on gitHub and I will be happy to contribute. – Abhishek Feb 27 '14 at 07:03
  • Did anything come of this @Abhishek or Rafael? – TomDunning Jan 29 '19 at 01:27
  • That was a long time ago @TomDunning I can't recall what happened to this. Sorry. – Abhishek Jan 29 '19 at 04:42
  • No problem, I was just hoping there was a chunk of code sat in a repo somewhere. – TomDunning Jan 29 '19 at 09:23
