Solderbox is a compact semimodular synthesizer, made in collaboration with Jakob Haq. It is heavily based on Jakob's own modular rack design (which features a lot of modules made by hand). The app is designed to offer a set of modular functions that is both comprehensive and eclectic, including several tools for generative synthesis, random signals and the surgical mangling of audio waves and modulation signals. A lot of effort went into making everything sound and behave as analog as digitally possible (with the exception of the unashamedly digital Entropy lo-fi effect processor). Additionally, the built-in Instability Engine injects the subtle fluctuations simulating the effects of crosstalk, leaky signals and expired electrical components. This is a living instrument with a soul of its own. - Full Audio Unit compatibility (AUv3 instrument, audio effect) - Universal design (iPhone, iPad, MacOS AUv3) - Built-in Pulsequencer (LFO-based generative melody generator with custom scales) - 4 mode Low-pass filter (6, 12, 18, 24 dB) - 3 voice polyphony - Drone mode - Stackable patch cables - DIY Lo-Fi digital delay circuit emulation - All synth settings exposed a AU Parameters (for automation and MIDI learning in your host of choice) Find the user manual on ruismaker.com

The Guitar Analyzer app is a tool for analyzing and fine-tuning your acoustic or electric guitar: - A highly accurate guitar tuner with a cent scale indicator - An automatic scale tuner for all strings - A sound analyzer with multiple types of visual graphs for both the entire fretboard and individual strings - A sustain meter with sustain measurement by duration and factor - A dual custom sound oscillator for certain tasks where you need to hear the resonant frequency of an object or the beats between two specified frequencies - Conveniently select from over 50 well-known guitar brands to create your own list of guitars to explore and quickly switch between them - Choose from three string tunings (standard 6-string guitar, standard 4-string bass, and custom tuning for up to 12 strings in any key from 127 MIDI keys across the entire octave range) - Adjustable microphone sensitivity, noise threshold, and a choice between 2 types of amplitude analysis (peak and RMS) With this app, you can accurately tune your guitar, adjust the scale, and even choose the best guitar from several. By recording the sound across all frets for each string, you can use the displayed graphs to identify fret defects or nut placement, see unevenness in the sound in different places, see where the problem might be by changing the pitch shift of the frets, find the "dead note" and its position on the fretboard, as well as the resonant frequency of the instrument

Verdict

The call

The clearest difference is rating: Solderbox at 5.0 against Guitar Analyzer's 4.0. Solderbox also leads on price ($12.99 vs $19.99) and ratings volume (27 vs 1). Guitar Analyzer's advantage is update cadence (weekly vs every 6 weeks). On ads, in-app purchases and monetization model there is nothing between them.
