¿its possible make studio recordings with Trisquel?

Take a look at these digital audio workstations - both are libre.

LMMS - https://lmms.io/
Ardour - https://ardour.org/

Both are very feature-filled and have large, helpful communities.

Ardour is great. specially when you are connected to instruments and recording or editing sound waves that you are creating.
My dad has a great collection of old jazz LP'S AND CASSETTE TRACKS, that I did record from into a digital format, using ARdour. It was long and lot of consuming time, because I end buying a LP player and duaL DECK cassete player, once I connected the equipment and Spending around 500 dollars, the interface to a i-5 desktop works good. i USE A FIBER SOUND CARD FOR BETTER DIGITIZING SOUND,
about LMMS, i CANT say I use it.

AUDACITY
My favorite one and THE latest one IS AUDACITY, WORKS AWESOME AND SPLENDID, HAS A LOT OF PLUGGING AND YOU COULD RECORD THE SOUNDWAVES directly from YOUTUBE USING A pc AND CONVERT IT FROM MP-3, WAV, AIFF, CAF, BWF, FLAC, Ogg/Vorbis.

Is best you read,and decide what you want to use it for.

They are all free and under GPL LICENSE.
Yes, it is possible to record and edit under trisquel.

and i ever think what libre-software in a recording production has a different sound

you know about this?

Is it possible to differentiate itself from the rest with a software-libre sound?

Well,, the closest answer is in the quality, compression, and speed rate of what you are recording.. Yes sound waves can be manipulated. example: FROM MP-3, WAV, AIFF, CAF, BWF, FLAC, Ogg/Vorbis.

I hope that you understand me. another example: high definition sounds waves recording occupies more memory in the hard drive, sata or usb device is not as filming, but just audio. you have to read the help files in audio conversion you are making withing each program and search in the internet for more details.

Greetings everyone,
I want to offer a helpful request to the Trisquel developers (and all GNU distro developers), but not sure where to post it.

My end-user experience has me wishing for this to be implemented:
Please have Installation scripts run on the display screen for the end user to view the commands and procedures.
Learning the OS is a IMPORTANT opportunity and this will assist in that.
At minimum show the prcedure that will be executed with the major commands to be used as a static illustrative image.
The installation is (in my opinion) the first and the most important task for the end user that may be new converts to the free source community.

Thanks for all your wonderful efforts, cheers!

This is what I achieved with proprietary software without being an engineer

but the format and hosting are libre software

Saravia:

1.- Congratulations... I am proud of you..

2.- You can take a look at Musix or Ubuntu Studio most of the software, if not all, that is installed there is also in the Trisquel repos so you can install it with apt-get.

However, I suggest going with parabola for most up to date software. This type of software is constantly improving. And for someone used to proprietary is better to go with the best.
