MIDI Channels
MIDI allows for 16 discrete channels for sending data. When dealing with MIDI triggers, Sound Forge software needs to know what MIDI channel to look at for receiving the trigger. The channel this information is sent to in Sound Forge software depends on the device sending the MIDI messages.
MIDI Clock
A MIDI device-specific timing reference. It is not absolute time like MIDI Time Code (MTC); instead it is a tempo-dependent number of “ticks” per quarter note. MIDI clock is convenient for synchronizing devices that need to perform tempo changes mid-song.
MIDI Controllers
MIDI controllers are a specific type of MIDI message. Sound Forge software can use MIDI controllers to trigger events and playback of sound files. Consult your MIDI sending device to see what controller messages it sends.
MIDI Notes
MIDI notes are a specific type of MIDI message. Sound Forge software can use MIDI notes to trigger events and playback of sound files. Any MIDI sequencer or controller will send MIDI notes.
MIDI Port
A MIDI port is the physical MIDI connection on a piece of MIDI hardware. This port can be a MIDI in, out or through. Your computer must have a MIDI-capable card to output MIDI time code to an external device or to receive MIDI time code from an external device.
MIDI Time Code (MTC)
MTC is an addendum to the MIDI 1.0 specification and provides a way to specify absolute time for synchronizing MIDI-capable applications. MTC is essentially a MIDI representation of SMPTE time code.
Mix
Mixing allows multiple sound files to be blended into one file at user-defined relative levels.
Multiple-Bit-Rate Encoding
Multiple-bit-rate encoding (also known as Intelligent Streaming for the Windows Media platform and SureStream" for the RealMedia G2 platform) allows you to create a single file that contains streams for several bit rates. A multiple-bit-rate file can accommodate users with different Internet connection speeds, or these files can automatically change to a different bit rate to compensate for network congestion without interrupting playback.
Note: To take advantage of multiple-bit-rate encoding, you must publish your media files to a Windows Media server or a RealServerG2.
Musical Instrument Device Interface (MIDI)
A standard language of control messages that provides for communication between any MIDI-compliant devices. Anything from synthesizers to lights to factory equipment can be controlled via MIDI. Sound Forge software uses MIDI for synchronization purposes.
Noise-shaping
Noise-shaping is a technique which can minimize the audibility of quantization noise by shifting its frequency spectrum. For example, in 44,100 Hz audio quantization noise is shifted towards the Nyquist Frequency of 22,050 Hz.
