Does the audio format listened to by dejavu have to be the same as the one I want to recognise？

测试可以mp3和mp4进行比较，不用音频格式都相同。个人会进行后缀的统一修改，都用.mp3

They don't have to be the same codec. I believe dejavu uses ffmpeg to decode to wav before fingerprinting and recognising.

However, from my own experience, I find that they do need to be the same sample rate. A track fingerprinted by dejavu from a 48kHz version of an mp3 will not match with a 44.1kHz version of the same song. Open to correction on that though.
