Quite often, novice musicians who try to play some original high-speed instrumental part of another artist, encounter the problem that they need to slow down the music, that is, slow down in relation to the original sound, for example, to better parse the notes played. The same thing can happen when you want to use some kind of musical fragment for your own purposes when creating your own composition or audio sequence for presentation. There may be many options. However, it should be clearly understood that such actions can only be performed to a certain limit, and even the most ordinary software players will work for use.
How to slow down music, and can it be done?
Indeed, if earlier with the audio files to perform some actions to change the tempo (so that the result does not look, to put it mildly, absolutely absurd) was almost impossible, then with the advent of specialized programs this has become quite simple. True, it should be understood that not all sound formats are equally susceptible to slowdown or acceleration. But the most important thing is that when you automatically change the tempo of a musical fragment, if you do not take appropriate actions, an automatic change in pitch is also made. In other words, if you slow down the music, the initial key will be lowered, and vice versa. Along the way, it is worth noting that not all programs designed for this allow you to perform the described actions in such a way that the final file sounds without distortion.
Programs that slow down music
However, if we talk about software, in the simplest case, you can use utilities like Audio Speed Changer, which are designed for unprofessional use, and in which it is enough to simply set the desired level of deceleration for the supported type of sound files.
The result is not the best, but all operations are carried out very quickly.
If we talk about how to slow down the pace of the music so that there are no distortions in the resulting fragment, or side effects are not present, it is better to give preference to professional and semi-professional audio editors. Among the most famous are Adobe Audition (formerly Cool Edit Pro), Sony Sound Forge, Audacity, etc. In all such applications, you can slow down music using the special Stretch tool. There are already more settings.
In the filter itself, you need to set the slider level with the slider, but the most basic thing is not to change the pitch (Transpose or Pitch Shift). To set the desired constant level, the main tab is used, for floating (for example, with a slowdown from the beginning to the end of the fragment) - Gliding Stretch.
Typical Actions in the FL Studio Sequencer
As for how to slow down music in the popular musical studio sequencer FL Studio, everything is simple. The fact is that even when loading a WAV fragment from a studio or user set to the selected channel, it is immediately resampled, in which the sound just adjusts to the set tempo.
When changing the general tempo of programs, it issues a request to change the tempo and all the WAV files loaded into the sequencer. But with MP3 files, this option does not work. By and large, you can initially convert an MP3 file to WAV, upload it to a sequencer, and then change the tempo as you like.
Online resources
The most lazy users can be advised to slow down the music by focusing on online resources, of which you can find quite a lot on the Internet today. The essence of the operation is to upload a track to the site, select the level of tempo change, wait for the end of processing and download the result to your computer. True, you should immediately pay attention to the restrictions on the size of the processed files and the maximum rate of change of pace. Again, using them is far from the best solution.
