• Loud, Aggressive, and Powerful Sound Shaping • Extreme compression, capturing vintage analog nuances and colors • Unique 'flatten' feature to preserve character while restoring dynamics • Fast sound refining with impact and sustain controls • Single or multi-band, with filter slopes ranging from 6dB to an impressive 192dB • Creative noise gate: smoothly blend from single to multi-band • Parallel compression and optional master Brickwall limiter • Intuitive workflow for effortless adjustments • Low latency, waveform display of the pre and post signal • Advanced Responsive Design, portrait and landscape views | Light/Dark Theme • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Smash is all about generating explosive energy for your beats and instruments! Squash, squeeze... SMASH your sound, or simply get that magical gentle touch when you seek refinement and finesse. Behind its unconventional and flashy appearance lies a series of boosted upward compressors meticulously designed to include the specific nuances and colors of vintage analog devices. The plugin can operate on either one or three frequency bands and provides a couple of filter slopes ranging from a subtle and transparent 6dB to an impressive 192dB! The workflow is optimized for simplicity and intuitiveness, enabling effortless transitions between subtle adjustments and complete alterations with its up to 120dB of upwards compression. Yes!, FAC Smash can push the sound to its extreme limits, potentially creating a "sausage-like" signal. But fear not — the 'flatten' feature steps in to restore dynamics while preserving the aggressive character, giving you the best of both worlds. The built-in noise gate circuit at the input adds yet another layer of sonic sculpting possibilities. Whether acting on the entire signal or individual frequency bands, this circuit can transform your sound, expanding your creative possibilities. But the magic doesn't stop there; FAC Smash offers parallel compression, an optional master Brickwall limiter, and a waveform view of both the pre and post signal! You'll have a clear visual representation of your audio as you sculpt it to perfection. The documentation is available at fredantoncorvest.com/FAC_Smash.html

Learn Synths teaches synthesis by letting you play it. Every lesson is the same synthesiser with a few more controls revealed. Lesson 1 is four waveforms and a scope. Lesson 49 is a full instrument with sequencing, effects, sampling and MIDI. Nothing is a recording. Every sound is synthesised as you touch it, and the waveform on screen is the one going to the speaker. THE COURSE 49 lessons in nine tracks: subtractive synthesis, sequencing, drums, FM, wavetable, additive, effects and mixing, sampling and MIDI. Each screen shows only the controls it teaches. A short quiz finishes every lesson. BEYOND THE COURSE Seven genre studies, from house to dubstep, as drums, bass and lead playing together with every knob open. Tours of Sylenth1 and Serum 2, section by section, each linked to the lesson that taught it. Eleven challenges: hear a classic sound, build it by ear, get scored. INSTRUMENTS AND PLUG-INS The synth, drum machine and sampler on their own, with presets, a sequencer and effects. The same three as AUv3 plug-ins for GarageBand, Logic, AUM and other hosts. MIDI USB, Bluetooth and Wi-Fi controllers, a MIDI monitor, velocity, mod wheel, pedal and aftertouch. The first three lessons are free. One purchase unlocks everything, forever, on all your devices. No subscription, no account, no ads. Sylenth1 is a product of LennarDigital. Serum 2 is a product of Xfer Records. Images used with permission.

Verdict
The clearest difference is price: Learn Synths at Free against FAC Smash's $9.99. Learn Synths also leads on rating (5.0 vs 4.3). FAC Smash's advantage is ratings volume (6 vs 1) and iOS requirement (16.4 vs 18.0). On ads, in-app purchases and device support there is nothing between them.

Learn Synths is free to download; FAC Smash costs $9.99 up front. FAC Smash sells 3 one-off in-app purchases and Learn Synths sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Learn Synths holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: FAC Smash has 6 ratings behind it against 1, so its average is the more settled of the two.
