Octave Analyzer tool for iOS

Share

 

The Octave Analyzer tool for iOS performs real-time spectral analysis in whole or 1/3-octave frequency bands.

The Octave Analyzer tool is built into SignalScope Pro. It is also available in SignalScope and SoundMeter via in app purchase.

The Octave Analyzer can analyze up to two audio input channels simultaneously (this requires a two-channel input device).

The Octave Analyzer can be configured with several options that are common to overall sound level meters. These options include time weighted exponential average levels with fast, slow, and impulse response times as well as the equivalent level, which expresses an average signal level over the total measurement time. Flat, A, and C frequency weighting are also available.

The Octave frequency spectrum appears within a bar graph which can be adjusted in its vertical scale either manually or automatically. In addition to current levels within each frequency band, maximum or peak levels may also be displayed, depending on which level type is selected. A data cursor allows specific levels at specific frequencies to be identified. The entire graph can be saved either as an image in the iOS photo library, or as a high resolution PDF file within the app.

Additionally, in SignalScope Pro, Octave analyzer data may be exported to CSV, MAT, or tab-delimited text files. Data export is also possible in SignalScope and SoundMeter with the optional Data Acquisition Upgrade available via In-app Purchase.
