n-Track Studio 6

Recording & mixing
Records and plays back a virtually unlimited number of audio and MIDI tracks
VST, VST3, DirectX and ReWire effects can be added to each channel/track
Volume, pan, aux sends & returns and effects parameters can be automated: you can "program" fade-in/outs, cross fades, boost the volume of a track when there is a solo etc.
Live input processing allows to process with plug-ins live signals. Record the 'dry' (unprocessed) signal while processing and reprocess the recording later - i.e. play a guitar through a distortion plug-in then change the distortion after the recording

Soundcards & audio interfaces
Supports 16 and 24 bit single and multichannel soundcards at sampling frequencies up to 192 Khz
Compatible with Asio, WaveRT, WDM, DirectSound and MME audio drivers, which means that n-Track can work with almost any soundcard available today with the lowest possible latency
Multichannel soundcards or more than one soundcard are supported: you can record multiple tracks at a time and output to more than one stereo output. Each output channels has its own master channel effects and volume control

Effects
Built-in effects include Reverb, Compression, Parametric & Graphic EQ, Echo, Auto-volume, Pitch Shift, Chorus, Multiband Compression, Spectrum analyzer
Includes the n-Track Drums drum synth/step sequencer module
Supports third party DirectX, VST 2.x, VST 3 and ReWire plug-ins
Supports VST Instruments and DirectX Instruments synth plug-ins: sample-accurate MIDI tracks can be sent to VSTi/DXi software MIDI synths, without the need of expensive hardware MIDI synths
Supports ReWire technology by Propellerhead Software AB: signals from other programs (such as Reason, Ableton Live, Fruityloops and many others) can be mixed in realtime with n-Track's own channels

Supported formats
Imports and exports .wav, .mp3, .wma, .mid, .ogg, .flac, .aiff, .cda, .sng, .sgw audio files
Imports and exports EDL multitrack song files for exchanging songs with other multitrack programs
Sync to other programs or external devices using SMPTE/MTC or MIDI Clock sync, acting either as master or slave
Supports surround mixing for creating DVD audio projects using 5.1, 6.1 and 7.1 channels surround formats
Videos (AVI, MPEG) can be played in sync with the song in a dedicated video playback window
Once finished recording the whole song, you can mixdown all the tracks into a single wav file and to use it to record an audio CD track using a CD recorder or to distribute the song via internet using the built-in mp3 encoder
