Anyone is free to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software.
Reverb occurs naturally when a sound is created in an enclosed space, and reflects from the walls. This effect can be created digitally, and is most noticeable when a sound cuts out suddenly and then continues to echo, slowly getting quieter.
Flanging is a type of phasing where two signals are introduced milliseconds apart, and then the two signals are mixed together. The delay time is varied, creating a whooshing or jet plane like effect.
The DJ software lets you repeat certain effects or parts of a song as much as you want. It started with CDJ players, where there was a “loop in” and “loop out” pair of buttons. You had to time precisely when you hit the buttons to get the perfect loop.
A gate is similar to a compressor. However, rather than attenuating signals above a certain value, it attenuates weak signals. This can be used, for instance, to reduce unwanted background noise.
The DJ software features synchronized samplers with instant record and playback slots. Synchronized samplers let the DJ perform astounding remixes live.
The DJ software supports MP3 audio format. MP3 is the most widespread of the lossy formats. (MP3s at 320kbps are generally accepted as pretty indistinguishable from CD sound quality).
The DJ software supports AIFF audio format (lossless format). Be aware that they’re not as universally playable as WAVE files once you get away from Macs.
This feature will find beats in the music so you can assign them to certain sound, effects and songs. Usually a visible grid appears over the track spectrum.
With a mixing history feature, the software automatically saves your audio tracks, enabling you to browse lists of tracks played in past mixing sessions.
The software can automatically detect the key the music is in, allowing you to easily mix tracks with similar keys. This feature could help DJs in choose a suitable song to mix next.
