What are MOD Packers ?

Hi !

I often use EaglePlayer to listen to modules

Now, it's clear to me that there are some formats like "NoisePacker" or "The Player" which are a sort of "Packed ProTracker"

This is written clearly in EaglePlayer module info window

But what exactly are these MOD Packers ?

Are only a way to reduce the size of a standard ProTracker module or should they be considered "music formats" ?

Thanks in advance

These module packers create a smaller version of the original module (duplicate/unused patterns are removed, samples are (optionally) packed etc. pp.) which often can also be replayed much faster than a standard Protracker module.

Interesting info StingRay

So, they exist for performance reasons

Another thing that it's related to this issue is the quality of the converted ProTracker module

For example, ProWizard is able to rip MOD Packers and plus it converts them back to the ProTracker format

Always asked myself if there's some quality side-effects in the conversion

In other words, the converted module could be worse than original one ?

As i have packed many MOD's over my amiga time.. i can say without doubt.. the answer to quality is the mods sound exactly the same packed / unpacked and converted back into protracker.. except in the case of The player 6.1 is concerned as it may remove too much after the looped sample and you might get a click.. 1 byte to much removed.
I always believed it would be better to have 1 byte pass the loop before it cut the sample.
The player 6.1 is also the best at protracker packing + crunchmania.
if you dont want to convert but compress i would say crunchmania with sample compression.. crms using crmdata with the -s command is the best option or the xpk compressors which also has crunchmania sample compression.

Always thinked (don't know why) original could be better

Unless of a bug in the conversion, converted mods will sound exactly the same.
You may, however, lose some information such as sample names - you know, this place where a lot of things which are not actually sample names are written

I've never given it much thought but now that you mention it, it's quite funny that almost no one actually used the sample names for putting sample names.

I always thought ripping/converting software which changed the names was lame (Pro-Wizard was notorious for this).

Thanks for info

I see, sample names are removed from the packed ones

But as you stated, often sample names are not sample names

Because sample names can be anything without any meaning it is not important to have them for release. As we know sample names are used to give some more or less important info to the audience. I don't like to lose them.

I'm not sure but doesn't exists a mod converter the uses a loss format for samples?

The Player can optionally perform lossy compression on the samples.
