A bad GSM connection on a busy sidewalk, a bullhorn with feedback and a helicopter overhead, or a 1952 rockabilly guitar amp in a recording studio live room:
The Speakerphone audio plug-in gives you authentic speakers of any size together with their natural environments.

  Watch the video

All the walkie-talkies, distant transistor radios, upstairs TV sets, bullhorns, cell phones and guitar cabinets you will ever need. Speakerphone (a plug-in for MacOS and Windows) will add dial tones, operator, static, and you can select from a wealth of ambiences on either the caller or receiver's end.

400 speaker impulse responses, 23 microphones, 106 'Covers' (from blankets to car trunks), 53 Altiverb rooms and outdoor spaces, 5 gigabyte of ambiences and sound FX, and 12 DSP modules from Leslie to GSM compression, conveniently presented to you in well over 500 presets.

Take the tour by watching the video here or scroll down for some audio examples.

Apart from choosing from the hundreds of presets from the preset browser you can shape and mangle your sound extensively combining the many DSP modules.

Speakerphone 2 plug-in user interface all modules on


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. The more info button brings up additional info on the selected speaker impulse response.


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.

Dry Wet

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.

Sp2 Features distortion
Sp2 Features room
Sp2 Features cover


Emulate a speaker's or amplifier's over modulation. In the distortion module audio is first passed through the Pre EQ: a parametric EQ and a low pass filter with resonance. 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: amp models, 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.


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 and even real outdoor streets are available as well.


A variety of objects can cover a sound source. Blankets, suitcases, boxes, glass cups, car trunks, walls are just few. The pitch of these resonating little acoustics can ben adjusted.

Sp2 Features Telecom
Sp2 Features Gate
Sp2 Features Compressor


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


Classic gate, you can set it to duck or entirely mute the input. This can be used to create connections that drop out, to clean up guitar input, etc.


Emulate the pumping of video cameras, enhance the guitar input signal and there are presets for the extreme types of compression that are present in walkie-talkies and megaphones.

Sp2 Features Eq
Sp2 Features Modulation
Sp2 Features Radio tuning


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.


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.


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).

Sp2 Features Mic
Sp2 Features Bit crush
Sp2 Features Grammophone


Similar to the speaker selector, but here a microphone impulse response can be selected. The available microphone time and frequency characteristics of the microphones depicted, and therefore make it sound as if the selected microphone was used in the result. Use it to make an announcer speak through a typical announcer microphone, or to pick up a guitar cabinet using a classic microphone for the purpose, for instance a Royer.


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.


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.

Sp2 Features Leslie
Sp2 Features Delay
Sp2 Features LFO


This module emulates a Leslie speaker, typically associated with Hammond organs.
A Leslie speaker, on the inside, rotates a horn speaker for the mid to high frequencies, and it rotates a horizontal baffle below a downward facing low frequency woofer. The result is rich rotating sound utilizing the Doppler effect (pitch shifting that can be heard while a sound source moves to or from the listener)


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. The Cross feed parameter determines how much of the left channel signal gets fed into the right channel delay path.


Four Low Frequency Oscillators (LFO) and two envelope followers (env) for automated parameter control. Simply click and drag a cable to a parameter that you want to control with the LFO. The speed can be synced to the host's tempo and there is a wealth of different waveforms to choose from.
