Bit Crusher vs Talea

A digital degradation effect that combines two classic forms of lo-fi distortion: bit depth reduction (quantization) and sample rate reduction (decimation). Together they emulate the character of early digital samplers, 8-bit consoles, and vintage hardware with limited converter resolution. The signal is first quantized to a reduced number of bits, introducing the harsh harmonic distortion known as quantization noise. It is then resampled at a lower effective rate using a sample-and-hold stage, producing aliasing artifacts above the new Nyquist frequency.

Drums that know where the music turns. Every other drum generator asks what genre you want and how busy it should be. Talea asks where your music turns — and then plays it. HOW IT WORKS • Set the bars, the time signature and the tempo, and mark a section wherever the music changes. That is enough — chords are optional. • Talea works out which bars the form leans on: a section arriving, a phrase closing, the ending. Gold ticks on the timeline show you where, before you press play. • The fill lands in the bar before the turn. The crash lands on the downbeat after it. The louds and softs lift into the turn and settle after. • Press Generate. Press Next take for another reading of the same form. WHAT'S INSIDE • Fifteen styles. Ten for the kit: rock, pop, funk/R&B, jazz, bossa nova, samba, reggae, Motown, boom-bap, four-on-the-floor. Five for concert percussion: march, bolero, tarantella, swell and tutti. • Nineteen time signatures, in three families — simple, compound and irregular. Each style is written against the pulse of the bar rather than against "beat 2 of 4/4", so 6/8, 5/4, 11/8 and 2/2 are not special cases. A 7/8 rock groove exists because the rule does; so does a 6/8 march. • Five kits, all synthesised on your device: acoustic, 808, 909 — and Concert and Orchestral, which are the same voices re-voiced as timpani, tam-tam, triangle, tambourine, suspended cymbal and concert bass drum. • Section feels: half-time, double-time, broken, build and stop-time. The control names the bars it will change before it changes them, so a chorus goes half-time and nothing else moves. • Density, Motion, Fills and Swing — and a tempo you can type exactly, not just drag. • A real engraved percussion staff: two voices, hands up and feet down, beamed by the pulse, x noteheads for cymbals, ghost notes in brackets. • Export MIDI on General MIDI channel 10, or MusicXML as a percussion staff for NoteFlight, MuseScore, Sibelius or Dorico. A concert kit names its instruments properly on the way out. • Import a bass line and the kick locks to it. Import a drum part and Talea reads its style, density and swing off the file and moves the sliders to match — visibly. • Import from Anacru and its cycle rides over your bar as polymeter, phasing against it and realigning on a schedule the app shows you. • Fully offline. No account, no sign-in, no ads, no in-app purchases, no subscription. • Talea collects nothing. Nothing leaves your device. WHAT IT WILL NOT DO It will not adopt an imported drum part for you to edit hit by hit. Talea is a generator, and a pattern it could not regenerate is a pattern its own controls cannot touch. It will not pretend to be a polymeter sequencer. Talea counts in one meter, and an imported cycle rides over it as a voice rather than as a second bar — because the thing that lets one style library serve 4/4 and 7/8 is a single pulse map. It will not guess at a control it cannot read from a file. Anything it is unsure of is left alone, and said so. Talea is by Songdeed. Pairs with Anacru for the polymeter, Mediant for the chords, Continuo for the bassline, and Melisma for the words.
