MPTrim (resurrected), and WavTrim

I've just came across this a google search, and a forum search found it originally posted by rridgely here..

What exactly can mpTrim do for you?
  • mpTrim can trim MP3s - removing silent or unwanted parts.
  • mpTrim can adjust the volume of MP3s. Volume change can be manual or automatic (volume normalization).
  • mpTrim can fade-in/out MP3s (to fix abrupt beginning/ending).
  • mpTrim can clean-up MP3s and recover wasted disk space.
  • mpTrim keeps the music quality intact, no matter how many times you process an MP3, because it works directly in the MP3 format without having to decode/re-encode. That also makes it very fast.

It's an amazingly simple application ran from an exe file. I've just been fading out a few mp3's, and it takes less than a second to work. Select fade out time (1 click), save or save as (1 click). Done.

Available here: MP3 Trim.

There's also Wave Trim.

WavTrim was originally created to help extract audio tracks from CDs.

Audio-CD song extraction is not very accurate (you easily get a little bit of the end of the previous track, or of the beginning of the next track). It is possible to trim each track by hand (using a regular WAV editor software), but that's tedious. So WavTrim first purpose was to scan and clean WAV files, removing silence and any leftover of another track.

WavTrim grew up as a multi-purpose WAV cleaner:

  1. Volume normalization (i.e. changing the volume to use complete 16-bits dynamic - that can help to get tracks from different sources sound similar)
  2. Batch mode (process several WAV files at once)
  3. and more... Just try it!

I haven't tried WavTrim yet, but MPTrim also retains all ID3 Tag information.

EDIT: Sorry guys, I meant to put this in the freeware thread. Must have had a senior moment. :(

From my personal experience WavTrim even at the least aggressive setting can still screw up a wav file which is the reason you really need to listen to the beginning and ending portions of a wav file after using it.

With MPTrim when trimming/editing some VBR LAME encoded MP3's you may sometimes have to fix the MP3 header in for instance Foobar2000 (available via right clicking an MP3 in the playlist window).

Although both programs do have some drawbacks as mentioned above I still use them and have been using them since around the year 2000.

That's a sure fire way of really f'n stuff up especially with tracks from say the 1980's that don't have heavy compression compared to the clipressed stuff of nowadays - really ReplayGain is required to get a similar sound level.

I've been using a little app called MP3Gain for a while now to do that stuff.

While MP3Gain is good for getting stuff to a similar volume level for instance with portable MP3 players it actually modifies the mp3, which is why I only use the ReplayGain feature in Foobar2000. Of course the MP3Gain way assures 100% compatibility with everything the MP3 is played in, whereas the Foobar2000 ReplayGain only adds the ReplayGain values in the tag's (ID3v2/APEv2, etc) of files so it doesn't actually modify the file itself.
