Nice, are you one of the initiated?  Myself I'm not a geek, I have an IT guru who teaches me everything. He posts on HydrogenAudio. He taught me to use foobar, which is a great programme: it's free, it takes very little of the computer's resources (memory and cpu usage), it's extremely customisable and it's development is boosted by fans who desing extremely usefull tools. It has a nice, minimalistic skin; it supports by default a lot of the unsual formats like FLAC, APE, AAC, MP4, OGG, etc.; it rips audio cds, it converts from any format to any format (given the proper encoders), it has Replaygain, it manages tags - you can edit tags, get tags for full cds from freedb.com, change tag types (idv3, idv2, ape), it has album art display, it has Cover Search, an engine that looks for album covers on the web, it has timer options (I can leave it playing when I go to bed and after the tracklist is finished, he shuts down the computer), etc., etc... I'm a fan!

Does it? Why so?
If you convert 192 to wav and back again to 192 you lose quality?

Another method is to adjust volume in a Wave editor.

Yes it is ... it doesn't change the audio at all, just adds two headers. BTW: The only thing to keep in mind when using Replay Gain is to not calculate it for single tracks ... always select the entire album. Otherwise you might boost silent tracks too much in relation to the other tracks of the album.

The player I use for audio files, foobar2000, has a very interesting option called "replay-gain". It allows you to scan your whole database of audio files (of any kind) and then it brings the volume of all the tracks to the same level. Or, you can pick a selection of audio files and to the operation. However I don't often use it because it doesn't work by boosting the volume for the low-volume files (I wouldn't want that anyway), but by bringing down the volume for the louder audio files. That affects my listening experience in a bad way because my speakers and earphones are weak and don't allow me to avoid feeling the volume has decreased. |

Then all you have to do is to configure Winamp to use replace gain (preferences -> General -> Playback), and all the files will have a constant volume.
The other option is to re-rip the files using a ripping software (like CDex) which allows to normalize the audio during extraction. But this can mean a loss of quality ... I prefer the approach of Replay Gain, which essentially just determines the peak level of the files and then stores that info in the file, so that the volume can be adjusted automatically during playback.
Of course Replay Gain doesn't have an effect on playback on a portable player (at least I don't know any which support it) ... but my Creative Zen has volume normalization, maybe your player also has such a feature.

I like to rip my CDs in to MP3 and listen to them in random order either on my MP3 player or using Windows Media Player.
One problem I have is that some CDs have a lower volume than others. So for one particular CD, I have to turn up the volume, when a track from that CD comes on, and turn down the volume when it finishes.
Does anyone know of a way of boosting the signal volume inside an MP3 file so that I won't have to keep adjusting the volume for those tracks?
