Digital imperfections - modelled accurately! BitJuggler is the most complete audio AUv3 available today to simulate vintage digital processing and to recreate digital imperfections. Whether you'd like to go down memory lane to create that 80's digital sound from early personal computers, add vintage sampler character to your audio tracks, or shape your audio beyond analog simulation: BitJuggler will deliver the digital imperfections with painstaking accuracy. Go beyond bit crushing BitJuggler covers all your basic bit crushing needs, with various quantization schemes such as linear, a-law and mu-law quantization and with an optional envelope follower. In addition, the audio resampler with a variety of resampling algorithms easily produces that creative digital aliasing sound. Add musical noise BitJuggler also includes speech and transform codec simulators to accurately generate musical noise as you would get from transform codecs such as MP3 or AAC. A GSM speech codec adds spectrally shaped noise by employing linear predictive coding (LPC). Or you can keep it simple and experiment with dithering and perceptual noise shaping! Pre and post emphasis for further shaping of imperfections BitJuggler ads options for pre- and post emphasis for digital clipping, quantization and resampling to provide unique capabilities to further shape the effect of the bit crushing process. Visualize changes BitJuggler has a unique visualization feature: it will show the errors introduced by bit depth and sample rate reduction in real time. The ultimate plugin for educational purposes: allow students to hear and see the imperfections that are being introduced. Keep it moving Modulate bit depth and resampling properties with the integrated low-frequency oscillator (LFO) and generate moving sound scapes in which aliasing and quantization components travel in time and frequency. The ToneBoosters BitJuggler app captures the microphone (or external sound card) input and processes the signals in real time. To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others. ToneBoosters BitJuggler will appear in the list of Audio Unit extensions for effect plug-ins. Key features: - Wide range of options for bit crushing and resampling - Pre and post emphasis to shape the sound - Undo/redo, and A/B comparison - Color themes for the user interface - Adjustable colours for every filter section - Max screen support in Garageband - Optimised for iPad and compatible with iPhone and iPod Touch - Efficient, low CPU usage What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.
BLEASS Dragonfly
This audio effect plugin offers a unique approach to tremolo, allowing music producers to add dynamic modulation to synths, vocals, and melodies. It syncs tremolo effects with input frequencies, MIDI notes, or sidechained signals for creative sonic textures.
- Pitch tracking for self or sidechain modes
- MIDI input for precise triggering
- Manual rate and amplitude control
- Adjustable smoothing, stereo, attack, and release
- Wild mode for saturation and waveshaping
- Animated visualization of effect rate

BLEASS Dragonfly is a completely new approach to tremolo effect which brings new sonic possibilities to all music producers. Make your synths, voices or any melody “vibrate” in correspondence with its own frequencies, or with external basses and leads! Just like in Billie Eilish’s song “Xanny”, Dragonfly helps you achieve the same effect as when the voice gets modulated by a heavy bass. BLEASS Dragonfly automatically syncs the tremolo effect applied on a track using various triggers: First, you can use the pitch tracking module on either the input audio track (“self mode”) or a sidechained audio track (“sidechain mode”). You also can use the midi input to trigger Dragonfly with accuracy: the tremolo will automatically sync with the notes’ frequencies. Finally, a manual mode allows you to set a fixed frequency. Then you can finetune your settings by adjusting the fine, factor, smoothness, stereo, attack & release. The “Wild” mode applies a waveshaper to the signal to produce a subtle saturation. The final tremolo effect rate is mirrored by the flapping wings of the Dragonfly. BLEASS Dragonfly is also available for Mac & Windows (AU / VST3) https://www.bleass.com/dragonfly/ ________________________________________________ Technical description: SOURCE stage: - MANUAL: Tremolo rate is set by the Rate knob. Tremolo amplitude is set by the Amplitude knob. - MIDI: Tremolo rate corresponds to the rate of the lowest MIDI note received by the plugin. Tremolo amplitude corresponds to the velocity value of this note. - SELF: Pitch tracking on the input signal gives the tremolo rate. Tremolo amplitude matches the input signal’s amplitude. - SIDECHAIN: Pitch tracking on the sidechain signal gives the tremolo rate. Tremolo amplitude matches the sidechain signal’s amplitude. - SOURCE CHANNEL: Sets the channel to be analysed for SELF and SIDECHAIN modes. - AMPLITUDE: Sets tremolo amplitude in MANUAL mode. - GAIN: Sets the input gain in MIDI, SELF and SIDECHAIN modes. DRAGONFLY stage: - RATE: Sets tremolo rate in MANUAL mode. - FINE: Offsets the detected pitch value by +/- 0.5 semitone in MIDI, SELF and SIDECHAIN mode. - FACTOR: Detected or set rate is multiplied by this factor to give the final tremolo rate. - SMOOTH: Sets the smoothing duration of rate variations. - STEREO: Sets phase difference between left and right channels. - ATTACK: Attack duration of the effect. - RELEASE: Release duration of the effect. - MODE: SIMPLE is a basic tremolo. WILD uses complex waveshaping for warm and saturated effect. - WILDNESS: Sets waveshaping strength in WILD mode. - VISUALISATION: Dragonfly wings are animated to match the rate and amplitude of the effect. Green label on the left indicates the input MIDI note and rate. Blue label on the right indicates the applied MIDI note and Rate. MIX stage: - GAIN: Output gain of the effect. - DRY/WET: Dry/wet balance. NOTE: This is an AUv3 effect which needs a compatible host that ideally offers audio sidechain or MIDI FX routing (such as AUM, Cubasis 3 or Logic)
