AX24 has been used by DPA Microphones for recording a Super Audio CD with a number of stereo comparison and demonstration recordings of a grand piano. The recording is made in DXD on AX24 giving the most accurate and transparent recording possible.
On this SACD the artist Niels Thybo plays seven of his own compositions on a grand piano, miked up with different microphone kits from DPA. Each kit is suitable for various microphone placements.
On the SACD tracks the different microphones and posisions can be evaluated on each played composition.

DPA issues also a booklet with a describtion of a number of useful waysto record and amplify a grand piano using DPA microphones. As every piano, room, and player is different, all setups should be regarded as guidelines. There are no strict rules and there is no substitute for using your ears to adjust the sound to your liking.
No equalization, compression, or external effects have been added to the files. All stereo pairs are normalized to -2 dB FS PCM, allowing true impulse responses of the different pairs to be compared.
