Tunchy

Tunchy is a simple audio application built for DJs that offers a host of mixing options for music files coming in WAV, MP3, and M3U formats.

Barebone interface

Limited to only four channels, each with a couple of options for music control, Tunchy is an archaic-looking tool designed for mixing music with fairly limited options.
The program’s interface is split between four panels, out of which one holds the mixing decks and another offers the music importing options. The other two host the list of songs that DJs might want to mix.

Limited features

There isn't a list of options Tunchy offers to its users, but mostly a couple of mixing decks with afferent buttons. DJs can set manual or auto-crossfading between songs in case they decide to upload a list of audio files and also configure fade in and fade out sequences.
To fully control the speed of the song, they can set four tempo and pitch levels. File format support is only limited to WAV, MP3, and M3U. If you plan to mix songs coming in other formats than these three, you're out of luck.
It also allows users to set different hotkeys for each command, this way giving DJs full keyboard control over the interface. Except that, there isn't much else users can enjoy using Tunchy.

Final opinions

Tunchy delivers the minimum of features DJs need to run a decent mixing session. It won’t offer any sort of support for external amplifiers or other music devices. Also, other file formats, except WAV, MP3, and M3U, aren’t supported so users should choose other apps in case they plan to import a songs in FLAC, WMA, or OGG file format.
However, if you plan to hold a house party with whatever songs are available, Tunchy will do just fine, but you must keep in mind this isn't a portable tool so you’ll need to install it in your host system in order to have it run smoothly.
