Hi, I'm trying musicid, but I want know, how much time in seconds must be sample song (wav 16bit 44khz stereo) for to call
your service ? Inside your example there is a song with 22 seconds about. Is it that ? 22 seconds ?
Also, to be sure that recognition is right, I have to make several calls in different parts of the song?

Thank you

There are two types of MusicID queries you can do: MusicID-File (for full audio files like MP3s), and MusicID-Stream (for microphone recordings, usually with background noise). MusicID-File requires about 15 seconds of audio in the file to identify, while MusicID-Stream requires between ~3-6 seconds of audio. You only need to call MusicID once to identify the song.
