Are there any good music mixers available, equivalent to Windows "MP3 Tunes"?

Question

In Windows my dad used to have a program called MP3 Tunes. I have tried running it with Wine, and it worked. But strange things kept happening to the program, so it's not a reliable way to play music.

Basically I just want to have 2 players (in a single window) with these features:

• Preloading tracks in a player without immediately starting them.
• Fading from one track to the other.
• A timer on each player.

These features are also desired, but not required:

• Microphone input.
• Prelistening before loading a song in a player (through a seperate sound card).
• Pitch/Tempo control.
• Just being able to browse folders in the filesystem (without things like a music library).

Here are some screenshots of the program to clarify what I'm looking for:

Answer 1

Take a look at the java based Ultramixer.

Features of the free version:

• AAC/M4A file support
• Fullscreen and tray mode
• MiniMode Player
• Variable pitch range (up to -/+ 50%)
• Database-driven file archive
• Realtime-BPM Counter
• Support of skinning for the user interface
• Cue points
• 3-Band-Equalizer / EQ-Kill-Buttons
• Import / Export of M3U lists
• FileArchive detail search
• Manual Talkover
• Monitoring over headhones
• Multi-soundcard support
• Automix function
• Switchable fading modes

Installation instructions from Ultramixer community forum.

Answer 2

I'm not sure where to look if you want an application that has only those features, but there are a couple of very robust audio mixing solutions for Linux, closer in functionality to Garageband for OSX.

Try Ardour, billed as "a complete digital audio workstation"

Or LMMS - the Linux Multimedia Studio.
