So this app has a lot of advantages that we are going to comment on next, basically what we can do is record audio directly, using a microphone or even a mixer, in turn if you want to digitize the classic cassettes or old records you can do itIn short, we can do a lot of things, copy existing tracks on top of others, monitor volume levels, etc.
Best of all, this program has easy editing thanks to a fairly well-designed interface that becomes productive, with a easy access to all available tools and easier and faster in the most used. You can make the amount of changes you want, quickly edit files that have a large size, mix and edit a large number of tracks without any kind of limits with all the editing tools that it has.
In addition to everything mentioned above, you can change the tone without having to alter the time and vice versa. In turn, it is possible to eliminate background noise from any sound in general to make it as clean and crisp as possible. It even has an equalizer, low sounds can be expanded so that they sound obviously louder, but in a clear way and without saturating, adjusting the volumes in a very simple and intuitive way.
In short, it is a fairly simple program to use, but above all it is too powerful, both for people who are looking for a slightly more professional approach but who at the same time want to have something simple to work on and also for those who do not have much idea of this but who want to start little by little to get into the world of audio editing, an ideal program for both extremes and even middle ground.
