Bit Maestro is an AUv3 bit crusher that goes beyond regular bit rate reduction, allowing you to affect and manipulate your sound at the individual bit level. Taking inspiration from the legendary ‘OTO Biscuit’ it enables you to selectively mute or invert individual bits in your audio signal. As it does this it creates distortions in your waveform, introducing a wide range of harmonics. Bit Maestro pushes this concept even further, allowing you for the first time to even rearrange the order in which the bits are evaluated, reassigning their value and giving rise to waveform distortions not previously seen in any distortion module. This sound can be further enhanced in a number of ways. - Three filters are available (low pass, low shelf, high shelf) which can be used to tame or enhance the aggressiveness of the sound. - A delay line to inject a different groove into a bar or provide a basis for interesting mod effects. - A modulation panel to continually evolve your sound and introduce further aliasing effects. The end result is a plugin that can introduce huge depth and power to your sound. One that offers you the nuanced control to design your perfect digital distortion, ranging from subtle warbling to huge crushing sounds that can transform any drum or bass line. Supports: - AUv3 - MIDI control - Inter-app Audio - Audiobus

FlangeII Dual Stereo Flanger Plugin (AUv3) FlangeII is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro, GarageBand or AUM. Overview FlangeII is a dual stereo flanging machine with a vintage vibe! As well as traditional super-wide stereo flanging effects, FlangeII can also produce all manner of swirly modulated goodness by running the independent flanging engines in parallel or series. Selectable modes allow quick access to finely-tuned settings under the hood that "just work", from subtle to extreme - just the thing if you find some flangers to be overly complex with too many parameters! Set Rate and Depth to taste, adjust the stereo Width, then you can even add some gritty Drive for some "analog" warmth. Controls Active - Bypasses the effect (Off) or selects one of the following processing modes: Stereo - Two independent flangers for the left and right channel, with LFOs 90 degrees out of phase for a stereo effect, determined by the Width control. Parallel - Two independent stereo flangers for the incoming audio, which are then summed together at the output stage. The LFOs for each of the four flangers are 90 degrees out of phase for a stereo effect, determined by the Width control. Series - Two independent stereo flangers with Flange I processing incoming audio, which is then passed on to Flange II for a double-helping of flangey goodness at the output stage! This is potentially the most dramatic flanging effect, especially with the Width set to maximum as each of the four flanger LFOs are 90 degrees out of phase. The following controls apply to each flanging stage, referred to as Flange I or Flange II: Flange I/II - Toggles the Flange I or Flange II processing engine On or Off. Rate - Sets the rate of the flanger LFO in Hz. Depth - Sets the depth of the flanging effect. Mode - Selects one of four different modes. Each mode configures several "under the hood" settings - think of each mode as a mini preset for internal parameters. Modes range from subtle (I) to extreme! (IV). The following controls are global: Width - Adjusts the stereo width from super-wide to monophonic. Note this only adjusts the "wet" flanged sound so your original stereo image remains intact for the "dry" signal. Drive - Applies an optional amount of warm overdrive to the flanger processing only, for a bit of a vintage vibe! Mix - Balances the processed audio with the incoming / dry signal. At zero, the output is totally dry, and at 100%, the output is totally wet and flanged to the max! The flanging effect can sometimes create loud resonant frequency peaks that could result in clipping. To protect against this, soft limiting is applied at both the flanging processing stage and at the final summed output. If the input levels are high, this can add to the "analog" like sound of FlangeII when compression and saturation occurs. About The UI Not everyone likes the UIs of my latest (2025) plugins - I get it. However, the simplistic and generic approach allows me to (a) 99% focus on the DSP, sound quality and CPU performance, and (b) significantly reduce the development (and potential maintenance) time, which is reflected in my pricing.

Verdict

The call

The clearest difference is rating: FlangeII at 5.0 against Bit Maestro's 4.8. FlangeII also leads on update cadence (every 6 days vs fortnightly) and price ($1.99 vs $4.99). Bit Maestro's advantage is ratings volume (26 vs 2). On ads, in-app purchases, monetization model and device support there is nothing between them.
