Oscilloscope Spectrogram: Powerful Audio Analyzer App and Plugin
OSCILLOSCOPE & SPECTROGRAM is a versatile audio analyzer app and audio unit plugin that offers a range of powerful features. It can be used as both an Audio Unit and standalone app, making it convenient for different workflows. The app allows users to view up to three seconds of audio on the screen, with the ability to pause and scroll horizontally to browse back in time. Pinch-to-zoom functionality enables users to zoom in and out for a closer look at the audio waveform.
One standout feature of Oscilloscope Spectrogram is its ability to display both the oscilloscope and spectrogram separately or overlayed together. This provides users with a comprehensive view of the audio signals. The frequency trigger mode is particularly useful, as it helps identify the precise frequency and MIDI note of sounds in the spectrogram.
The app offers both stereo and mono views, and the level-based trigger mode includes lookahead, pause, and zoom features. The XY mode allows users to visualize stereo correlation. The app also automatically adjusts the FFT size to fit the zoom setting, ensuring accurate analysis. The bark-frequency scale spectrogram offers detailed analysis at both low and high frequencies.
One notable advantage of Oscilloscope Spectrogram is its use of sinc upsampling when zoomed in. This provides a close approximation of the audio output from the audio interface after digital-to-analog conversion, offering more accurate visual representation.
