Preset selector and wet dry slider
Select one of the many hundreds of presets from the preset browser that appears when you click in the preset bar. The Wet Dry control gradually moves between processed and unprocessed (Bypassed) sound in a very elaborate way. A movement from WET to DRY will gradually open up filters, including the speaker IR, and diminish the effects of modules like Distortion and Codec each in a unique way. The overall result of a movement from WET to DRY is a seamless opening up of the sound from the complete preset to unprocessed sound. If, for instance, you have your mix sounding from a jukebox in the back of a bar, you can slowly open up the sound to full stereo buy dragging the WET/DRY slider. Or click the right most KICK text to make the slider move from wet to dry, automatically, at a speed determined by the KICK slider.

Sample bay
You can build complete environments for the speakers right here, via mouse clicks or MIDI.
Several gigabytes of samples and music are installed with Speakerphone, free for use in your production. 5 tables of twelve samples are accessible at a time for playback via mouse clicks or MIDI.
The samples range from extras like knobs and closing car doors to ambiences and music, and they are used throughout the presets that come with Speakerphone.
You can drag samples from the sample bay to your tracks and vise versa. And you can add your own library as well.

Tuning
Simulates the various effects of a radio receiver dial.
Vertical movement of the cross-hairs changes the frequency of inter-modulation side tones, and when the cross hair is moved out of the horizontal center, the reception of the signal worsens (distortion and noise is added).

Delay
Mono or stereo feedback delay with a high pass or low pass filter in the feedback loop. The delay can be synced to host tempo, in which case the delay time rotary knobs are exchanged by notes. Clicking on a note then brings up a note-value selector box.

Codec
(Cellular) phone connection protocol simulation. Apart from emulating cell phones the codec can be tweaked to make whispering presets, robots and vocal synthesizer effects.

Mod
The modulation (mod) module offers five types of classic modulation effects, available in the top left popup.
These are: Tremolo, Chorus, Phaser, Flanger or Vibrato.
DEPTH controls the amount of the modulation effect.
SPEED controls how fast the modulation oscillates. Speed can either be set in FREE mode or in SYNC mode. SYNC ties speed to the host sequencer's tempo and displays it with a note value.

Phono
Gramophone effects simulator.
Influence a pitch curve due to 'Wow' (effect of an off-center hole) and Curve (a bumpy record). Also Add ticks and crackles that knock holes in the input audio.

Gate & compressor
These can be used to create connections that drop out, to clean up guitar input, emulate the pumping of video cameras and there are presets for the extreme types of compression that are present in walkie-talkies and megaphones.

Equalizer
Five types of frequency filters.
Low and High shelving filters, High pass filter and low pass filter and two bands of parametric equalization with adjustable q-factor.

Room
Convolution reverb, powered by Altiverb, for room, outdoor space, hall, resonant enclosure, and reverb gear simulation. Room creates reverb based on recordings of actual spaces ranging from a railway station hall to the cockpit of a MIG fighter plane. Samples of spring and plate reverbs are available as well.

Distortion
Emulate a speaker's or amplifier's over modulation. In the distortion module audio is first passed through the Pre EQ. If you engage it by clicking its on/off button you can control both a parametric EQ and a low pass filter with resonance in the same graph. Bandwidth, or Q, for the Parametric EQ can be adjusted with the small rotary control. Next, the signal hits the PRE gain, which typically amplifies so the waveform will become more or less distorted in the next module: the Distortion Type. The actual distortion model is selected in the TYPE popup. Some are amp models, others are wave shapers, all of them are further controlled using the CURVE graph at the bottom of the distortion module. POST-gain controls the distortion's output volume. You can also click the connection-button in between PRE and POST to have post gain automatically decrease when pre gain increases and vise versa. Finally you can Mix the distorted signal with the undistorted input signal using the MIX control.

Crush
Word length reduction and sampling rate reduction.
Drag the cross hair down to reduce word length (reduce from 32 bit input to 2 bit output). Move to the left to reduce sampling rate. To maximize aliasing effects the most crude of sample rate conversion algorithms lies beneath the Crush module.

Speaker module
At the heart of the speaker simulator lies a library of recordings of different speakers, often referred to as Impulse Responses, or IR's.
When you click a speaker category icon, like the phone or the radio, a browser window appears that lets you select a speaker in that category.
The impulse responses by themselves capture many characteristics, both in frequency and time, of the sampled speaker. The speaker module lets you select a speaker impulse response, and it shows its corresponding photograph. Double clicking that photograph brings up additional info on the selected Impulse Response If you want to check out which speakers we have for you then select 'speakers below.
