Publisher Description
Spectrolite visualizes sound as spectrograms in real time.
Spectrolite supports constant-Q spectrograms, which use a logarithmic frequency scale for a display where musical notes are evenly spaced. Spectrograms based on linear and mel frequency scales are also supported.
The display covers the full frequency range of human hearing. Intuitive touch panning and zooming lets you dive in and explore the spectrograms in detail. Gain, Q, and other parameters can be adjusted in real time and instantly apply to the display of past signals as well as future ones.
The Pro in-app purchase adds grids and scales for time, frequency, and amplitude, as well as a spectrum view and a tap-to-measure function. This expands Spectrolite into an audio measurement tool that you can use to measure frequencies, musical pitches, amplitudes, and durations.
Version History A fast horizontal swipe will now scroll the display without friction all the way forward to real time or back to the beginning of the recording.
In the tap-to measure feature available with the Pro in-app purchase, the resolution of the musical note display has been increased from 1 to 0.1 cents.
The musical notes frequency scale available with the Pro in-app purchase now shows grid lines for tenths of semitones when zooming in far enough. 2.4 3d ago Fixed a bug that could cause a failure to resume operation after an audio interruption such as an alarm or incoming call. 2.3 Feb 5 Fixed a bug that caused an incorrect analysis bandwidth to be used for constant bandwidth and and mel spectra in the spectrum mode.
Improved spectrogram image quality and reduced flicker when zooming out in the vertical direction.
Updated to meet new technical requirements from Apple. 2.2 12/11/2025 Bug fixes and performance improvements 2.1 02/17/2025 Added support for constant-bandwidth and mel-scale spectrograms.
Fixed a bug that could cause the colors of scales to fail to update immediately after being changed in the settings. 2.0 11/15/2023 Fixed a bug that caused the tap-to-measure function of the Pro in-app purchase to display the left channel measurements for both channels when measuring a stereo input.
Performance improvements and documentation updates. 1.4 03/17/2023 With the Pro in-app purchase, you can now measure the frequency and amplitude of a frequency component simply by tapping on it. 1.3 07/07/2022 When using an external stereo audio interface, display each channel in a different color.
Added a preference for the audio input source, for choosing among the built-in microphones on devices with multiple microphones, or among the input connectors of certain external audio interfaces.
Added a preference for choosing the polar pattern (directivity) of internal microphones that support multiple polar patterns.
Fixed a one-sample glitch that occurred periodically about once every two minutes.
iOS versions older than iOS 12 are no longer supported.
