I don't know if this list will be complete, but it will certainly be updated with new programs, also according to your comments in the comments. This time we talk about music, so for musicians we do not talk about how to convert audio tracks or mix music but about free software tools that support those who know and play music, both professionally and, above all, on an amateur level, for those who are learning.
The programs listed below are all free without limitations and also simple to use, useful even for those with little experience, both in music and in computers .
1) Sonic Visualizer is a powerful audio visualization tool for Windows, Mac and Linux.
Although graphically it is very rough and unattractive, this program is able to reproduce a wide range of graphic effects and display them in separate panes, layered one above the other.
Sonic Visualizer can be extended via downloadable plugins.
VST plugins are not directly supported, but Windows users can get them, with some limitations, through Audacity's VST Enabler.
2) SlowMP3 is a program for slowing down music playback.
It allows you to change the speed of an MP3, so you can see which notes are played and transcribe them slowly.
The small and simple program requires Java on the computer.
SlowMp3 also has a Karaoke mode for removing vocals from a song.
3) BPMinus is a modern audio manipulation software similar to SlowMP3 with different options.
The editing tools allow you to change the tempo of the music by slowing it down or speeding it up, while keeping the pitch.
You can change the pitch and balance the sound with the Stereo Mix.
BPMinus supports almost all audio formats, but for some formats it is necessary to install additional plugins from the options tab.
4) GBK Music is a handy tool for finding chords and scales with ease
The program for musicians is useful for finding scales and chords for guitar and keyboards, for right and left handed, with graphic display.
5) Pitch Ear Trainer is instead a free learning program for those who want to train their ears to music.
This small program plays notes based on certain user-defined parameters and asks to identify them.
6) Forte Free and Musicore are two programs already described in the article on how to write the notes of a song on the computer and hear it while composing.
Especially the first one, it is really simple to use even for first-time musicians.
To these we can also add the Italian program Read notes .
7) Noteflight to compose music on your PC, write notes to print and download scores is not a program but a web application already described in another post.
8) Reaper is perhaps the most powerful free recording studio to download, although very complex and recommended only for those who know music well and can orient themselves with computer software.
Reaper had already been mentioned in the article Mixing and creating music by professional DJs on the PC with the best free programs.
9) Audacity is the best of the audio editor programs to edit music and recordings described in another article.
10) Audio Tuner is instead a program for musicians who have to tune or tune their instrument.
In another article, all the plans to tune a barge.
11) Notation Player to see the notes of each song while listening and save the score
