Audacity's spectrum analyser is limited to 8 kHz, where high quality audio files require a much higher spectrum.- tarec liked Spekta
My favorite spectrogram analyzer because is really fast and easy to use, even when it is buggy sometimes.
Used it a couple years ago. It did it's job good enough, even if it was a bit buggy. I liked it =)
Very quick and easy to use. Does what it says on the tin. Found it very useful when comparing formats and conversion settings before re-encoding a large batch of needlessly high-quality files.
