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.

Trinity is an effective integrated mastering solution for digital music production enthusiasts & professionals, containing a set of precisely matched and fine-tuned creative tools for achieving the desired sound and loudness. Focused on a reference-based mastering workflow, Trinity lets you work with an optional reference track whose sound you want to achieve, using a flexible spectrum analyzer to aid in comparing and matching. All controls and sliders are fine-tuned for ease of use, appropriate sensitivity and defaults, making adjustments easy and efficient. Everything is available on a single screen without any distracting menu-diving. 44.1, 48 and 96 kHz sample rates are supported, as well as the following audio file types for import: WAV, MP3, AIFF, MP4, AAC, ALAC (Apple Lossless). Note that very long audio files (> 20 minutes) are not supported. For a detailed guide on how to use Trinity, please visit our website! REFERENCE-BASED MASTERING: - In addition to the raw input audio file, another (professionally produced) track can be loaded as a reference - Easy and immediate switching between both tracks for comparison and adjusting the app's controls to attain the desired sound - Seek bars with waveform previews and one-click seeking - One-click section looping for focusing on a certain part of the track SPECTRUM ANALYSIS: - High-resolution and responsive FFT averaging frequency analyzer - Differential Spectrum feature can show the spectral differences between input and reference track for visual matching - Adjustable response time (averaging) - Precise Full-resolution or Smooth Half Octave Averaged display EQUALIZATION: - Transparent Low-Cut Filter with adjustable cutoff frequency and 12 or 24 dB/octave slope - High-Shelving EQ with either a gentle characteristic or a steeper 12 dB/octave slope and variable gain and frequency for fine-tuning brilliance - Up to three freely adjustable general-purpose peaking EQs - Visualization of overall response curve MULTIBAND DYNAMICS: - Three frequency bands with adjustable crossover frequencies - Two selectable crossover types (custom-designed, smooth Trinity crossover or more surgical phase-corrected 24 dB/oct Linkwitz-Riley (LR4) crossover) - Ratio, Attack, Knee, Release and Gain controls per band - Global "Compress" control and per-band Density control with intelligent make-up gain replace the traditional "Threshold" controls for easier operation - Precise gain reduction meters - The compressor section's response can optionally be included in the spectrum response curve display - Solo toggles to isolate bands for precise tuning NORMALIZATION: - Automatic base normalization of input file - Two realtime normalizers (pre- and post multiband section) with optional analog saturation for transient cleanup, additional loudness maximization or sound shaping MULTIBAND STEREO PROCESSING: - Simple but effective Three-Band Stereo Width (M/S) controls from Mono to Extra-Wide - Fine-tuned with love, individually per band, for keeping perceived loudness and giving useful results - Basic Goniometer (Phase Scope) WAVESHAPER: - Optional Wave Shaping with five selectable algorithms - HQ toggle for High-Quality Oversampling LIMITER / CLIPPER: - Either a look-ahead brickwall limiter or a hard clipper can be used in the final stage depending on taste - Adjustable Attack and Release - Adjustable output ceiling from -2 to 0 dBFS METERING: - Responsive and accurate stereo output meters - RMS or LUFS (Momentary, Short Term, Integrated) metering - PEAK metering always shown simultaneously - Normalizers with accurate saturation / clip indication EXPORT: - Export as 16/24-bit standard or 32-bit float WAV file - Optional rectangular dithering NOTE: Trinity currently does not support running in the background, so your audio will stop as soon as you leave the app or lock the device. This might change in a future update.
