Free Download Audio Samples
Free sample test tones are provided in 160k MP3 format. For each of the 3 tones on this page is the associated spectrogram. The spectrogram shows the frequency and amplitude of each file. Note the tight response of the warble tone vs the smooth averaging and rolloff of the 1/3 octave pink noise.
The CDs sold on this site, as well as the files available for download to paid members, are full 16bit uncompressed WAV files.
