I have a Sony Network Walkman which converts all my tracks to the Sony Atrac3(plus) format before copying them to the player. Most of my tracks I transfer are originally in mp3 format. I want to increase the volume on all of these with the minimal amount of loss.
What format does Cool Edit 2000 convert the mp3 to when it increases the Amplitude (using the Amplitude option in the Transform menu)? Is it RAW PCM? If I choose the output format to be the same as this one then I should save a conversion step - correct?
eg.
Original: mp3, Final: Atrac3plus
Steps: mp3 -> (RAW PCM)? -> raise amplitude and save as (RAW PCM)? -> mp3 -> Atrac3plus
If I can miss the second mp3 stage I should save on sound quality loss I hope.
Thanks for any help.

If you save from Cool Edit in PCM format (say 44.1kHz, 16bit which is the CD standard) then download that direct to the player you should minimise your losses - if the Sony software handles wave files prior to converting to atrac. Alternatively I believe there are programs which manipulate the level flag of mp3's directly without decoding the file, which would be even better if it worked.

Do you know of any such software?
I tried the RAW PCM method but that created a .pcm file that the Sony software (SonicStage) didn't recognise. I then tried it using the Windows PCM (*.WAV) format, but then I lost all the ID3 tag information (Artist and Title) - which I should've known. Also, I don't know if this format is the intermediary format used by Cool Edit 2000
The type of software you mention is probably the best method.
Thanks

I know William Rose has investigated mp3 editors in detail - hopefully he will jump in on this one. Try searching for "mp3 editor" on Google. I've tried searching this forum for what I had in mind and can't actually find it - I'll come back if I come across it later.

Search the Web for a program called MP3GAIN. Believe it is freeware. While I have not tried it, it will reportedly do what you want.
Regards.
