I have a live stream of audio which i try to fingerprint & search using the GNSDK(3.06) java wrapper. My code is based on the musicid_stream sample.

I use the code: 

gnMusicID.fingerprintBegin(
GnFingerprintType.kFingerprintTypeGNFPX, 
44100, 
16, 
2
);

/* write audio to the finger printer */
gnMusicID.fingerprintWrite(audioData, audioData.length);

/* does the finger printer have enough audio? */
gnMusicID.fingerprintEnd();

where audioData is byte[] of the audio's PCM

I was looking for information in your API reference with params you recommend using:

  • how long should the recording be? minimum seconds?
  • should I try GnFingerprintType.kFingerprintTypeStream3 \ GnFingerprintType.kFingerprintTypeStream6 as the GnFingerprintType?
  • use higher sampling rate?

My audio buffer might be at any position during the song as I record a live audio.

please suggest.

Thanks.

  • I have tried them but none of them made the percentage of recognition any better (it is very low), and I am looking for some information that can't be found in the API reference. – ilazar Jul 08 '14 at 09:59

I figured out that the music stream was not clean and figured out how to get better stream...

FYI: I currently use 6 seconds of recordings and the above params and get quite good results.
