Rives Audio Test CD Version 2

The Rives Audio Test CD is a unique and inexpensive way to determine room and speaker response. It has 1/3 octave test tones from 20 Hz to 20 kHz. The test tones are very precisely calibrated for a flat response. Each tone is a single track, so that once a room mode has been found, one can put the track on repeat mode and determine where the 'hot spots' or areas of highest sound pressure exist to properly treat the room.

In addition to the flat 20 Hz to 20 kHz tracks there is an additional set of tracks that are also 1/3 octaves from 20 Hz to 20 kHz. The only difference in this series of tracks is that it is not flat. It is precisely calibrated to compensate for the non-linearity (particularly in the lower octaves) of the Radio Shack analog SPL meter. This meter is very reproducible, but not very accurate. It is also very inexpensive and easy to obtain. For this reason these tracks were made to compensate for this device.

Unique to the Test CD 2 are added partial tracks of various Mapleshade recordings. Mapleshade, also located in Maryland, makes some of the purist and cleanest sounding recordings. They are very revealing. Rives Audio has found them to be essential tools in subjective listening. One piece of music has been mastered in a variety of ways to test phase and other common problems.
