TfxEcho vs TB Lowtone

TfxEcho is an echo effect AudioUnit Extension plugin. It uses delay lines which are inspired by BBD (bucket brigade device). BBD is used in various analog delay unit and is known for its warm and dark sound. The delay line uses fixed length buffer and an artificial clock to sample input signal in variable sampling rate. When the delay time is changed, the delay line can produce pitch change effect which is similar to the behavior of the BBD based analog delay unit. The delay line is inspired by BBD, but it is not emulation of the any particular BBD. Unlike the typical BBD based delay unit, frequency range of the delay line is not limited. The delay line is capable to capture signal in higher frequency up to about 22KHz. Features AudioUnit Extension - Delay Time: From 20 ms to 1200 ms - Feedback: From 0 % to 100 % - Adjustable lowpass filter and high-pass filter. - Modulation rate: From 0.01 Hz to 10 Hz - Modulation width: From 0 ms to +/- 10 ms - Delay time can be synced to tempo provided by the host application. Host Application Host application uses system audio input as an audio source and processed audio signal is routed to the system audio output.

TB Lowtone is an innovative bass synthesizer app and AUv3 plug-in featuring three analog-simulated, voltage-controlled oscillators with a large variety of waveform algorithms, continuous pulse-width modulation (PWM), Frequency Modulation (FM) and oscillator hard sync, complemented by a voltage-controlled noise synthesizer, parameter modulation a re-designed non-linear voltage controlled filter. TB Lowtone is the world's first bass synthesizer featuring loudness-domain harmonic synthesis, creating deeper, more consistent and production-ready bass sounds compared to conventional synthesizers operating in the (linear) amplitude domain. TB Lowtone also features an AI randomizer that generates new patches with a single click, and which learns from the patches you have already created to generate new, personalized patches! Loudness-domain synthesis Loudness perception of tones and harmonics is known to be highly non-linear and intricately frequency and level dependent. Equal loudness contours, or Fletcher-Munson curves demonstrate this drastic effect for sine tones, which is especially relevant for low frequencies. The loudness of a synthesizer bass note, and all its individual harmonics, will therefore depend strongly on what note you play on your synth's keyboard. To overcome the resulting inconsistencies in loudness and timbre, TB Lowtone features innovative, loudness-domain synthesis algorithms that adjust each harmonic individually to compensate for loudness deviations across frequency. Modulation and FX TB Lowtone provides two extended low-frequency oscillators (X-LFOs) featuring a wide range of waveforms. The LFOs can be beat and key synced, with a configurable onset delay and a specific number of cycles to run. In addition, a conventional ADSR envelope with configurable onset delay is provided. To top if all off, a gate editor designed to quickly put together modern production modulation patterns is available as well to modulate a range of VCO, VCN and VCF parameters. Reverb, chorus, and delay effects and a high-quality peak limiter are provided to produce production-ready sounds. Features: - 3 VCOs plus a VCN featuring a wide range of waveform algorithms - All VCOs support hard sync, pulse-width modulation (PWM) and frequency modulation (FM) - Lots of filter types for spectral shaping - 2 LFOs, one extra envelope and a gate editor for parameter modulation - Pro quality effects (reverb, chorus, delay, peak limiter) - Unique loudness domain synthesis algorithms - A smart randomiser that learns from your patches - AUv3 with resizable UI and dozens of color themes to choose from - Preset management including import and export options - Undo, redo, A/B switching 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.
