Audio Toolbox vs Quantum Sequencer Usage & Stats

Audio Toolbox is a suite of audio analysis tools for the iPhone and iPad. It comprises both audio waveform generators as well as a highly accurate Fast Fourier analysis engine, an audio oscilloscope and various frequency detection and tuning tools. The Tone Generator allows you to create anything from a simple sine, triangle, square, or sawtooth waveform as well as white and pink noise. It also supports log and linear sweep tones with definable range and level and complex wave construction using sine waves. The later is great for teaching audio theory with its DTMF and complex tone generation tools you can build complex waveforms and then analyse their component parts using FFT and the oscilloscope. Build DTMF, triangle, square or saw waves using multiple sine waves etc. The Audio Oscilloscope allows you to analyse directly from the tone generator or microphone. The scope features both free running and single shot modes with adjustable triggering options. The single shot mode automatically starts and stops capturing when short bursts of sound exceed a threshold. The oscilloscope also features a simple measuring tool to help measure duration and frequency of a waveform. The FFT Analysis section provides both Linear, Logarithmic as well as 1:1, 1:3 and 1:6 Octave modes. There is also an SPL meter complete with LEQ options and A/C weighting, log and linear Spectrograph and Mixer EQ modes for setting up audio mixers. All screens support 10x zoom, full screen and pause modes to aid analysis. There are also specific modes to detect peak frequencies, musical notes with cents offset, perfect for instrument tuning. Definable calibration tuning allows you to tune +/- 40Hz. Features: •20Hz-22KHz Tone Generator. •Sine, Square, Saw, Triangle, Sweep and MultiTone options. •Accurate 8K Fast Fourier Analysis. •32bit / 44KHz floating point audio sampling. •Standard ANSI/IEC A and C weighting curves. •Up to 64x oversampling. •Smoothing (alternative to averaging). •Automatic noise cancellation. •Automatic peak note / frequency and octave display. •Narrow band Linear and Logarithmic scalable displays. •Spectrogram display with Log and Linear Modes. •1:1, 1:3 and 1:6 octave display modes. •1:1, 1:3 and 1.6 Mixer tuning modes. •SPL (Sound Pressure Level) display. •Max, Min and Peak level capture. •LEQ Mode (Equivalent Continuous Sound Level). •Variable definable decibel scales. •Touch screen display of nearest point with frequency and decibel readout. •Audio Oscilloscope - Free Running and One Shot modes. •0.1 to 1000Hz timebase. •0.25-50x scope Magnification. •Definable trigger (leading and trailing edge). •10x zoom and full screen modes. •Pause facility freezes the live trace to aid analysis of data. •Camera Roll capture facility. •Export and Email CSV data from FFT or Scope. •Built in web server for transferring files. •Capture peaks over time facility. •Works on both iPhone and iPads.

Quantum Sequencer

Quantum is a performance midi sequencer which approaches music composition with an interactive creation processes - sometimes referred to as 'noodling'. Where pattern or piano-role sequencers are good for music forms (intro/verse/chorus etc) or grid entry, Quantum's approach is built around the idea of a step being the focus - think of the step as a single note or chord written on a music sheet then add a lot of extra notation (like probability of playing or ornamentation say). These highly detailed steps are then aligned into sequences (think melodies) that loop. You can have any length up to 64, but these can be further split into 4 sub-sequences that have their own set of sequencer parameters (like tempo, play direction, transpose etc). To enter step parameters such as note pitch, velocity, gated length etc, 16 general faders are available which allow you to draw, drag, select copy/paste, inc/dec & link together to edit values. These are also midi learnable (midi cc or nrpn) to allow you to use control surfaces or midi controllers. To aid you with faster control Quantum has loop actions which you can program in to carry out tasks when a sequence loops - e.g. transpose, randomise, start or load another sequence etc. With up to 24 sequences playing Quantum introduces a mixer page allowing you to blend midi velocities. Built on the MidiSequencer engine, midi FX, devices & Controllers are now possible per sequence. So why would Quantum be good for your setup? There are many midi enabled IOS & hardware synths that produce exotic timbres if you send them fast & varied midi controls that you just would not hear with keyboard playing or slow tempo tunes. Also, Quantum, embraces experimentation in melody creation and by copy/pasting allowing quick setup of arpeggios & counterpoint tunes that you can create & manipulate on the fly! note : This app sends midi information - you need to use it in conjunction with any midi enabled iOS synth app (e.g. Sunrizer) to hear sounds
