AudioSpect

AudioSpect is a software application designed to analyze the frequency of human voices obtained from recorded audio tracks.
It offers support for MP3 audio tracks and features just a couple of approachable options that can be tackled with ease, not only by those experienced with audio analysis programs, but also by casual users.

Easy installation and interface

The setup operation is a speedy job that shouldn't give you any trouble, since there are no unfamiliar options, mandatory software tools, or third-party components bundled with the installation kit.
When it comes to the interface, AudioSpect has a large window with a simple design and layout. It contains a sample file recorded in the MP3 filetype to give you a better idea of how it works.

Load and analyze audio tracks

While playing a sound file, the program measures the high and low frequencies of all human voices detected, showing their graphical representation in a bar spectrum.
You can set up the master volume by moving a slider to unlock the play button, as well as press the Ctrl key to stop or reset the playback. There are no other notable settings available.
For instance, it doesn't implement a feature for copying the graph as an image to the Clipboard, printing it, or exporting it to file. Moreover, it doesn't supply you with any technical details about the audio analysis, nor with explanatory symbols about the bar chart.

Evaluation and conclusion

Although it hasn't been updated for a long time, the application worked smoothly on newer Windows models in our tests, without any compatibility issues. It remained stable throughout its runtime, without freezing, crashing or prompting errors.
As expected from a compact tool, it had minimal impact on the computer's performance, using a low amount of CPU and memory. Unfortunately, it's no longer in development, which means that AudioSpect shall not received further updates.
