About

Room Impulse Response

Analyze the acoustic properties of rooms and loudspeakers. Record impulses or swept sines to generate Impulse Responses (IRs) and visualize various acoustic metrics like RT60, EDT, and clarity. Perform spectral analysis with FFT for detailed sound decay visualization.

Highlights
  • Record impulse or swept sine
  • Generate Impulse Response (IR)
  • View ETC with RT60 cursors
  • Analyze Schroeder curve (EDT, T10, T20, T30)
  • Spectral analysis with FFT
  • 3D waterfall plot for sound decay

Room Impulse Response measures audio characteristics of a room or loudspeaker. Start by recording an impulse, such as a handclap or balloon pop, or record a swept sine and use the built-in deconvolution to create your Impulse Response (IR). Now, view the ETC, with RT60 decay cursors, apply windowing if you wish, or trim the IR. Next, see these other graphs: ** Impulse, where you can play back the actual IR ** ETC, which includes cursors to read out RT60 times directly, and allows pinch-zoom gesture for trimming the file. Apple a window, and see the effects of the window on the ETC plot. ** Schroeder curve, with EDT, T10, T20, and T30 markers And then see these charts, all in either in Octave or 1/3 Octave bands: ** T20 or T30 (RT60) times ** Reverb Early Decay Times (EDT) ** Clarity C50 ** Clarity C80 ** CT times ** Definition ** Signal / Noise And then you can also do spectral analysis, using our FFT, which can be windowed, for analyzing loudspeaker response without reflections, or see the 3D waterfall plot to view the decay of sound in the room by frequency, over time. Works great with the internal iOS device microphone, or attach or iTestMic or iAudioInterface2 for fully professional results. See the other great apps by Studio Six Digital, including AudioTools.

Here comes the the crazy twin-sister of Ruismaker, designed for people who want to design their own percussion sounds from scratch. Ruismaker FM's simple, yet flexible synthesis engine lets you create anything from snaredrums, kickdrums and spacy toms to weird and unconventional percussive sounds and effects. Ruismaker FM is a unique drumsynth plugin (i.e. it does not use samples), which is coupled with a creative Euclidean sequencer when run in standalone mode. The plugin is fully AUv3 (Audio Unit) compatible: - Seamless integration with Garageband and other AU hosts - Audio Unit Instrument: making music on iOS doesn't get more convenient - Supports AUv3 Multi-Out in AUM and ApeMatrix - Each sound is modeled using authentic analog and FM algorithms; - Comes with dozens of unique customizable models - Does not use any samples; all sounds are synthesized in realtime, on the fly - Light on the CPU, so you can run lots of Ruismaker FMs simultaneously - Fully automatable parameters (requires host support) and MIDI CC controllable - Has its own preset manager The standalone sequencer is refreshingly different: - Program patterns using Euclidean algorithms - Powerful random feature and mutation probability settings per channel - Syncs with Ableton Link or MIDI Clock - Exports WAV and MIDI - Compatible with Audiobus 3 (including MIDI IN/OUT mode) - CoreMIDI In and Out - AU MIDI output for on-screen pads User manual available on Ruismaker.com
