Messages

choosePreset	preset-number [int]	The word choosePreset, followed by a number in the range 0-2, selects a preset for the omx.4band~ object. These presets are to be considered "starting points" and should be tweaked for your particular purpose or desired sound. The preset options are: 0: Standard - Appropriate for anything, all genres of music, movies, television viewing, etc. 1; Pop - Great for any modern genre including rock, country, trance. 2; Movies - Similar to standard but optimized for dynamic movie soundtracks.

mbagc_b3_atk	release-rate-coefficient (0 through 150) [int]	The word mbagc_b3_atk, followed by a number, sets the attack rate for band 3. The attack rate determines how quickly the compressor applies gain reduction. The value range is 0-150 on a logarithmic scale, with larger values indicating faster attack.
mbagc_b3_drv	release-rate-coefficient (0 through 150) [int]	The word mbagc_b3_drv, followed by a number, sets the gain in dB applied to band 3 before compression. Increasing the drive for a particular band applies more compression to those frequencies.
mbagc_b3_rel	release-rate-coefficient (0 through 150) [int]	The word mbagc_b3_rel, followed by a number, sets the release rate for band 3. The release rate determines how quickly the compressor returns to unity gain. The value range is 0-150 on a logarithmic scale, with larger values indicating faster release.
mbagc_b4_atk	release-rate-coefficient (0 through 150) [int]	The word mbagc_b4_atk, followed by a number, sets the attack rate for band 4. The attack rate determines how quickly the compressor applies gain reduction. The value range is 0-150 on a logarithmic scale, with larger values indicating faster attack.
mbagc_b4_drv	release-rate-coefficient (0 through 150) [int]	The word mbagc_b4_drv, followed by a number, sets the gain in dB applied to band 4 before compression. Increasing the drive for a particular band applies more compression to those frequencies.
mbagc_b4_rel	release-rate-coefficient (0 through 150) [int]	The word mbagc_b4_rel, followed by a number, sets the release rate for band 4. The release rate determines how quickly the compressor returns to unity gain. The value range is 0-150 on a logarithmic scale, with larger values indicating faster release.
meterData		The word meterData will cause output (by instantaneous command as opposed to metering-interval described by the meterRate message) of values which describe the current state of various internal levels of the compressor, and can be used to drive GUI objects to provide visual feedback.
meterRate	output-interval (milliseconds) [int]	The word meterRate, followed by a number, specifies the interval (in milliseconds) at which the meter data described above will be sent.
meters	metering-output-flag (0 or 1) [int]	The word meters, followed by a 1 or 0, turns the metering output on or off. When metering is on, a list of values will be sent from the rightmost outlet at a rate specified by the meterRate message. These values describe the current state of various internal levels of the compressor, and can be used to drive GUI objects to provide visual feedback.
lim_drive	pre-peak-limiting-gain (dB) [float]	The word lim_drive, followed by a number, sets the overall gain in dB before peak limiting is applied.
ngenabled	noise-gate-enable-flag (0 or 1) [int]	The word ngenabled, followed by a 1 or 0, turns the noise gate on or off. A noise gate is effective for reducing background hiss when no other signal is present. omx.4band~ features two noise gates: one that operates on the entire signal, and one that only affects higher frequencies, such as hiss.
ngthresh1	noise-gate-threshold (dB) [int]	The word ngthresh1, followed by a number, sets the threshold level (in dB below full scale) at which the overall noise gate will be engaged.
