About Spectro
Spectro is a freeware audio file analyzer for windows. Currently capable of reading FLAC, APE, MP3 and WAV files. Spectro lets you view vital data about compressed audio files and creates a spectrogram of the wave data. This allows you to quickly and easily spot quality issues with a file and also look for transcodes.
Spectro will soon support an automatic transcode detection feature and will be able to scan your music library for suspect files.

The latest version of Spectro is 1.0.93
This version fully supports 16 and 24 bit audio files (up to 192KHz sample rate), has a frequency cutoff indicator and can read pertinent metadata from compressed files.
At this point it should be very stable and well rounded.

You can download the latest version here. Feedback is always welcome.

Features coming soon
WavPack support is being finalized
Better zooming of spectrogram, scaling
Reduced memory overhead
Transcode detection
Scanning of multiple files
Saving spectrogram to PNG/GIF
Lots more ideas in the pipeline...
