OctiMax 4-band Compressor omx.4band~ delivers the signal-processing power of Octimax in a 4-band compressor. Cycling '74 MSP MSP Dynamics (signal) Left Input Channel TEXT_HERE (signal) Right Input Channel TEXT_HERE (signal) Left Output Channel TEXT_HERE (signal) Right Output Channel TEXT_HERE (list) Parameter Output TEXT_HERE (list) Meter Output TEXT_HERE TEXT_HERE TEXT_HERE Select a preset 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. Bypass processing and output the unprocessed signal The word bypass followed by a non-zero number will output the dry unchanged input signal straight out the outlet without any processing; followed by a 0, will output the signal effected by omx.4band~. Set the release gate threshold The word gating_threshold, followed by a number, sets the release gate threshold (in dB below full scale). When the signal is below this threshold, the release time of the compressor will be slowed by a factor of 3.

Increasing the drive for a particular band applies more compression to those frequencies. Set the release rate for band 1 The word mbagc_b1_rel, followed by a number, sets the release rate for band 1. 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. Set the attack rate for band 2 The word mbagc_b2_atk, followed by a number, sets the attack rate for band 2. 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. Set the gain applied to band 2 before compression The word mbagc_b2_drv, followed by a number, sets the gain in dB applied to band 2 before compression. Increasing the drive for a particular band applies more compression to those frequencies. Set the release rate for band 2 The word mbagc_b2_rel, followed by a number, sets the release rate for band 2. 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. Set the attack rate for band 3 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. Set the gain applied to band 3 before compression 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. Set the release rate for band 3 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. Set the attack rate for band 4 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. Set the gain applied to band 4 before compression 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. Set the release rate for band 4 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. Output internal state value data 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. Set the metering output interval The word meterRate, followed by a number, specifies the interval (in milliseconds) at which the meter data described above will be sent. Disable/enable the metering output 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. Set the overall gain before peak limiting is applied The word lim_drive, followed by a number, sets the overall gain in dB before peak limiting is applied. Disable/enable the noise gate 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. Set the threshold level for the band 1 noise gate 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. Set the threshold level for the band 2 noise gate The word ngthresh2, followed by a number, sets the threshold level (in dB below full scale) at which a noise gate will be applied to the treble frequencies only. Set the noisegate threshold The word noisegate followed by a number which specifies a value in dB, sets the noisegate threshold. Set the maximum gain applied by the multiband compressor The word mbagc_range, followed by a number, sets the maximum amount of gain in dB applied by the multiband compressor. This affects all four frequency bands. The compression ratio is fixed at infinity:1. Set the post-compression gain for band 1 The word outmix1, followed by a number, sets the gain in dB applied to band 1 after compression. Set the post-compression gain for band 2 The word outmix2, followed by a number, sets the gain in dB applied to band 2 after compression. Set the post-compression gain for band 3 The word outmix3, followed by a number, sets the gain in dB applied to band 3 after compression. Set the post-compression gain for band 4 The word outmix4, followed by a number, sets the gain in dB applied to band 4 after compression. Send all parameter values out the third outlet The word saveSettings causes all parameter values to be sent out the third outlet. Audio input Audio input, the signal or pair of signals to be compressed. Out leftmost two outlets: the input signals (if present), with dynamics processing applied. Out third outlet: parameter values in response to saveSettings message.

Out fourth outlet: meter data. When metering is turned on, lists of values will be output that describe various internal levels. See the description of the meters message.
