Normalization and such.

[BaronStragen]

Hello all, I have ported Rockbox to my Gigabeat F10 and I love it.  It beats toshiba's gigabeat software hands down with one exception....I have noticed some bass distortion in certain songs, and no amount of tinkering with the audio settings (eq and such) have been able to fix it.  I believe that some mp3's are recorded at different levels and I have wondered if anyone could create a normalization routine or option for the gigabeat.....like the root-mean-square method or such.  I'm sorry, I'm not much of a coder, more a media expert.  Is this a possibility?

Thanks
Chris

Hello all, I have ported Rockbox to my Gigabeat F10

And there was me thinking it was people like markun and toffe who did the port  

Being serious, Rockbox includes replaygain support.  Use something like Foobar to scan your files, and all will be good.

... unless the bass is clipping in the source file and then no amount of Replaygain will fix it...

Yep, if the source is clipping no amount of fiddling with it will help.

Sorry, I meant to say transferred instead of ported. My bad.  I'll give the replaygain a try and foobar seems to help. thanks.

I use dbPowerAMP to convert my files, that converts to a lot of formats and gives you the option of normalizing the volume.

gives you the option of normalizing the volume

If the source is clipping, normalizing won't help. If the source isn't clipping, ReplayGain is far superior to normalization as it's only touches the metadata.
