SpectroMark v1.2.0
- Spectrogram frequency axis now matches Adobe Audition's logarithmic display: the curve was measured from Audition and reproduced, so the low end is compressed and the 500 Hz to 15 kHz range is spread the same way.
Download SpectroMark.exe below. No install needed (bundles the .NET runtime, about 70 MB). Windows SmartScreen may warn because the exe is unsigned: click More info then Run anyway.
