RoomScope!

RoomScope turns your iPad, iPhone, or iPod touch into a room acoustics measurement and analysis tool. With RoomScope, you can measure a room impulse response and then calculate reverberation time, early decay time, clarity, and definition, as defined in the ISO 3382 standard. RoomScope Features:- Easily accessible measurement, excitation, and room analysis screens.- Export acquired data to CSV, TXT, or MAT files.- Save impulse response (IR) data to AIF, CAF, or WAV audio files.- Save high-resolution plots to PDF files.- Save plots to your devices photo library.- Import IRs acquired from other apps and stored in AIF, CAF, or WAV audio files.- Single-channel Measurement (for audio input devices that support it, multiple channels of data can be acquired simultaneously, but each channel is handled independently)- - Capture room impulse responses (IRs) directly using impulsive noise sources, such as starter pistols or balloons.- - Multiple triggering modes make it easier to capture an impulse.- - Capture IRs up to 10 seconds in length.- Dual-channel Measurement- - Measure room impulse responses (IRs) up to 16 seconds in length (up to 5 or 10 seconds on older iOS devices).- - View IR, squared IR, frequency response (FR) magnitude, or coherence in the measurement screen.- - Excitation signals include linear and log frequency sweeps (chirps) as well as white or pink random and pseudorandom noise.- - External excitation signals are supported with dual-channel (stereo) audio input hardware.- Analysis- - Calculate room acoustics parameters according to ISO 3382, including T20, T30, T60, EDT, C50, C80, D50, and D80, over the entire audio frequency range, or in whole or 1/3-octave bands.- - Plot room parameters versus whole or 1/3-octave center frequency.- - See the Schroeder decay curve plotted over the squared IR and set the decay curve integration limits with the touch of your finger.
