About

Aethron

Features
Read full description

Aethron is a minimal oscillator instrument for observing sound as waveform. Rather than a full music production app, Aethron is designed as a small sonic device for touching, layering, and reshaping oscillating sound. Add oscillators, tune frequency and amplitude, switch waveforms, invert polarity, sync phases, randomize signal states, and store the sounds you discover. Features * Multiple oscillators * SINE / SAW / TRI / SQR waveforms * Frequency and amplitude control * Fine frequency adjustment * SUM / SPLIT waveform display * RANDOM signal generation * POL +/- polarity inversion * SYNC phase reset * SOLO monitoring * STATES / STORE for saving setups * Automatic restoration of the last oscillator state Aethron is not a conventional synthesizer or a waveform viewer. It is a small instrument for touching invisible vibration through sound and waveform.

About

RKORD

Features
Read full description

RKORD is a field preamp recorder for people who record sound where it actually happens a temple courtyard, a stairwell, a street corner and want the character of a real preamp on the way in, not just a clean capture. THE CHAIN โ€ข Preamp โ€” analog-style soft-clip saturation. Push past 0 dB and it rounds off instead of digitally clipping. โ€ข Spread โ€” a delay-based stereo widener that lifts the low end as it opens, up to +6 dB. โ€ข EQ & Comp โ€” 3-band EQ and a FET-style compressor with a live gain-reduction meter, both zero-latency. โ€ข Tape Echo โ€” a short, modulated delay with real wow-and-flutter character, syncable to the built-in metronome. โ€ข Denoise โ€” adaptive per-band noise reduction that learns hiss, hum, and wind on the fly. BUILT NATIVE No web views, no bloat. RKORD is written directly against AVAudioEngine, so I/O latency stays in the single digits the chain sounds and feels the same whether you're capturing rain on a tin roof or bells in a temple courtyard. TAKES THAT NAME THEMSELVES Every recording is automatically named after where you made it no more scrolling through "Recording 47." Real-time waveform, one-tap rename, one-tap share. METRONOME, WITHOUT THE CLICK IN YOUR TAKE A silent visual metronome two dots tracing an arc, marking the downbeat that's audible only in your headphones and never printed to the recording. PRESETS Three nameable slots save your whole chain gain, spread, EQ, comp, reverb, tape echo, denoise so DRUM, FIELD, and VOCAL (or whatever you call them) are one tap away. Free to download and record. Unlock the full chain saturation, spread, tape echo, adaptive denoise, and presets with a single one-time purchase. No subscription, ever.
