First of all, thank you for getid3 !
Is it possible with getid3 to compute the checksum of a file, ignoring id3/APE informations ? My need is to generate such a checksum to check duplicate files with same audio information but with id3 tags wich are different.
I'd like a very fast algorithm... Is it possible for exemple to obtain very quickly all the positions of the audio frames of the file ? If we have this information, we could easyly get a checksum (md5 or other) of these part.
I found the linux shell cmd "avconv" wich can make something similar (give a CRC of audio frames) :
avconv -i MP3FILE -f crc - 2>/dev/null
But it is not very fast...
