Yes... In this case, unfortunately these are MP3 files converted to WAV.
Why?
As we wrote:
We know that the album "Children of the Future Generation" may not be entirely to your liking, but we will not disappoint you in the future

It was created in 2015-2018 in the LMMS program, so its limitations and our minimal skills did not allow for too much a lot

We decided to finally release the material so that it would not be left behind on the disk. At the time of its creation, and of course today, we like it, so why it not be liked by a larger group?

You still asking why?
The problem is that during our 10-year journey with music, we have had several "computer moves". We changed the studio three times, thoroughly rebuilding it. We replaced components in the PC.... So new platform means a newer system... The problem is doubled, because we're using Linux...

Terminal One LP was created entirely in LMMS 1.1.3 in the studio version 2.0.
Some time ago we changed the components on the computer again, which unfortunately made it impossible for us to work on songs from the past (Not all, but there were huge problems with VST plugins (Wine versions), not fully compatible LMMS versions, problems with file rendering).
If we wanted to get a WAV quality sound for this album, we would have to tediously rewrite the projects note by note. That's why we decided to release the album as it is.
Unfortunately, the files from the studio in WAV format do not exist - we do not have them, they were lost somewhere during this time. Today the studio is version 3.0 and we work on Linux Mint and FL Studio, sometimes there is LMMS in the background.
Identical situation concerns AERO51 album, where we moves from A51m studio v1.0 to v2.0... Initially AERO51 songs are produced on Windows in FL Studio, but later on new computer we changed it to Linux and free LMMS... And whole AERO51 album is remastered in LMMS, but the source files are mp3 from FL Studio from old A51m studio v1.0...
Sorry if we failed someone...
It's a bit sad, because, as you can see, sometimes it's not worth releasing an album just so as not to waste its potential...
For people something more matters than a heart put into music...
Oscilloscopes, charts, Hz, bits and bytes...
