TKT rename is working great the way it is - fast and accurate. However, the check sum will be useful when implementing the "auto volume adjustment" feature. TKaraoke needs to uniquely identify a song to avoid processing volume information over and over again.

I was looking for a auto volume adjustment plugin last night too. There's a program called Volume Logic that works very well but they only have plugins for Winamp, Windows Media Player and iTunes.

Back to check sum...CRC16 took about a minute to process a 450MB file using "Easy Hash 1.5" on my laptop. This does not mean all files need to be to use check sum. Could just identify unqiue songs based same file sizes first and process check sums for those files that have duplicate sizes.

1 minute per song is too long. I'm looking for less than 10 seconds time frame.

what about just do checksum for the 1st 1 MB instead of the whole file?

Will this first MB unique enough? If someone has some spare time, try to compute the first MB checksum (md5 hash preferred) on your entire collection of songs. Then try to see if there is any case that 2 different songs produce the same hash code.

I didn't know you can compute just the first MB. What tool/program can to do this? I'll give it a shot if it's possible.

As a programmer, you read the first MB and compute the hash from there (instead of reading the whole file).
