Classic FX is a complete sound effects processor and a mono-to-stereo enhancer with equalizer, effects and reverb, based on specially designed high-quality processing algorithms and suitable for any kind of audio sources. This application will add brightness and expand the sound space of any musical instruments, synthesizers, drums or voice. Unique and diverse effects with unified control parameters provide convenience and ease of customization, while at the same time plenty of room for individual expression and experimentation. Another unique feature of Classic FX is the Morphing option, based on complex effects matrix transformations, which allows you to control the dynamic transition between any two presets. While this can produce stunning effects, it's a breeze to control - you just need to move a fader or push a button. For more morph experimentation, this app has three LFOs to create more complex waveforms for changing morphs. Each LFO has different ranges, waveforms and can sync to the external BPM. Some of the other features of Classic FX: - Classic FX has 22 unique processing algorithms and 40 different presets. - Two slots in which you can use different effects and smoothly morph between them. - Three band equalizer with high / low shelving filters and middle peaking filter. - Easy to use algorithmic reverb, suitable for any sound source. - Limiter on output prevents any possible clipping. - Envelope follower for dynamic control of each effect. - Sequencer for rhythmic control of each effect. - Three special LFO in series to automate morphing. - Hot buttons to change the active effect slot. - Changing a group of parameters at the same time. - Echo module, Sequencer, and Auto morphing synced with the main BPM source. - The effect algorithm and its parameters can be saved as a preset. - Detailed application description and description of algorithms. - Quick info and description of each algorithm used in presets. Classic FX is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). Classic FX works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On MacOS, Classic FX can works both as a standalone application and as an Audio unit (AUv3) with DAWs and audio unit hosts like Ableton Live, Logic Pro, GarageBand, MainStage, Cockos Reaper, Plogue Bidule, Hosting AU, and other hosts that support AUv3 plugins. All application features are available on iOS and macOS.

About

BandDelay

This app offers a unique approach to sound design by splitting audio into 27 bands, applying individual delay effects to each. It allows for real-time manipulation of delay times, levels, and feedback, enabling complex rhythmic and sonic variations.

Highlights
  • 27 band realtime multiband delay
  • Frequency dependent level, delay time, and feedback
  • Tempo syncable delay times
  • Meta parameter for rhythm variations
  • AudioUnit for hosts like Garageband
  • Ableton Link compatible

Read full description

The multi-band delay BandDelay is an exciting tool for sound design and loop manipulation in realtime. In contrast to common delay processors BandDelay splits the frequency spectrum of the input signal into 27 bands and applies a separate delay unit to each band. The delay times can be synchronised to the host tempo generating nearly infinite rhythmical and sonic variations of the input signal. For each of the delay bands you can specify the delay time, the level and the feedback amount separately. These parameter changes can even be automised in realtime for glitch free rhythmical morphings. A few high level parameters let you change the delay times and feedbacks of all delays with the turn of a single knob. - 27 band realtime multiband delay. - Frequency dependent level, delay time and feedback - Linear phase precision filters for maximal transparency - Tempo syncable delay times up to 6 seconds. - Meta parameter for quick access to rhythm variations - Effect AudioUnit for use in hosts like Garageband, Cubasis, AUM and others - Full AU parameter automation - Ableton Link compatible - stand alone / Audiobus 3 / IAA

Verdict

The call

The clearest difference is price: BandDelay at $3.99 against Classic FX's $12.99. BandDelay also leads on review sentiment (100% vs 87%) and chart position (#199 vs unranked). Classic FX's advantage is update cadence (every 2 months vs every 8 months) and rating (4.6 vs 4.4). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
