User Manual:

ProSpec – Lite is a basic Real time spectrum analysis tool. It generates a spectrogram on the fly and supports 8kHz and 44.1kHz sampling frequencies.

You can record, playback, save and share the spectrogram for a given time frame. It provides a maximum frequency tracking facility with measurements both in dBFS, (SPL in paid version only).

Other features include:

– Time scale in seconds
– Update speed
– Dynamic range control
– Complete color customisation
– RGB option
– For audio engineers, an invert feature for live events in dark rooms
– Audio tool, allowing you to share, save and listen to the complete audio that has been recorded
– Saving, sharing and exporting the configuration (i.e. analysis settings: window size, dynamic range, FFT length and analysis window)

NOTE: If you are not satisfied or find any issues with ProSpec, please tell me in the discussion group before leaving negative feedback, I may be able to resolve your issue in an update and your input will be invaluable to ProSpec’s evolution. Thanks!

I developed this tool to use personally and I believe it has some use to others in the community. ProSpec also has some major advantages over other real-time spectrogram apps available for free. e.g. time scale (x-axis labels), saving settings and sharing the audio and images, and maximum frequency tracking. These are all features I wanted a single tool to have, unfortunately all others seemed to fall short, hence ProSpec has been developed to accommodate my needs, and hopefully yours.
