A very nice soundfile Martyn. :thumbup: :)

I agree with Dave's comments regarding the fact that the compression being applied is noticeable particularly in the attack of each note.

Martyn, the use of the word compression becomes a little misleading when applied to the reduction in size of files. When for example you convert a large .wav file into a .mp3 file the only noticeable effect is a reduction in sound quality which gets worse as the sample rate decreases. It doesn't produce the same type of effect as the 'compression' available in units like the Tonelab.

Hi Roger,
Yes it's unfortunate the same word's used for two different things but when reducing a large .wav file to an .mp3 one, I'd seen it described as 'compressing' the file, which is why I used the term. What I cannot fathom is why, by reducing its file size down from perhaps 50mb to3 or 4mb, the process itself doesn't seem to reduce the overall quality by too much yet seems to add that attack to the notes. Is it in effect removing some of the mid and bass frequencies, leaving the treble frequencies to become more prominent as a result?
I know someone explained to me the technicalities involved in reducing a file size from one format to another without degrading its overall quality too much but that did rather waft over my head somewhere, being somewhat technically 'challenged'. I'm just curious as to why the byproduct of this process should leave that clicking so much more evident.

Look forward to seeing you Sunday at the next club gathering - assume you'll be there?

Kind regards,
Martyn

I haven't noticed that effect when reducing .wav files down to .mp3 but I have a feeling that it depends what software package you use to carry out the process.

I use either Audition or Cool Edit Pro and choose MP3Pro audio coding.

I do plan to be there this Sun and look forward to seeing you.

I've been using Switch Sound File Converter - a free program so not sure which coding it uses, because Cubase4LE, which is the software program I mostly use for recording, doesn't have the facility to convert to .mp3s - I'd need to buy an upgrade to the full version to have that facility (according to its help files).

Audacity, a popular free recording software program I also use, does have the facility to convert to .mp3 but I don't know which quality or coding type it is (MP3Pro audio coding isn't present on its drop down menu of conversion options). Perhaps we'll have a chance to chat further about this on Sunday.
Cheers,
Martyn

Hi Martyn

It's OK to use the compressor if you can't hear it?????
A great guitarplayer once told me not to put the ration higher than 4:1 max, depending on the output from the guitar, and threshold at minus 3.
The name of that guitarplayer is Jerry Donahue and I followed that advice eversince, I think he shouldt know what his talking about.

Ok - here's a quick re-record having disabled the compressor setting on the Tonelab. It's a softer guitar sound now and I'd be interested in your opinion comparing the two versions.

That's a 1000% improvement - if there is such a thing . . . .

The problem with kit such as Tonelab,Line6 Pods etc etc is that the tools are available to make really good professional sounds, but the fact is, there is more scope to completely balls it up altogether - BEWARE !
