What are Tone-Pearls?

Tone-Pearls are small generators of etheric tone. They create the appropriate medium for musical tone.

What is the mechanism of effect of Tone-Pearls?

Based on the recognized principles of music, we created an instrument, the so-called Tone-Pearls. Tone-Pearls are small generators of etheric tone. They create the appropriate medium for musical tone. Tone-Pearls may establish a more direct and intimate connection to music. Metaphorically we may say: musical instruments and human ear will be extended in space by the effect of Tone-Pearls; thus, they might be considered – in this respect -- as musical instruments. We are aware that the above description is rather sketchy and hard to understand. For deeper understanding please, contact us.

Where can I buy Tone-Pearls?

Sorry, but Tone-Pearls are not commercial products, they are rather experimental products of a scientific study, tools of an investigation. There is no intention to sell them. However, you may enjoy Tone-Pearls recording technique by listening to our recordings.

Digital Downloads

What is Flac?

Free Lossless Audio Codec (FLAC) is a file format for lossless audio data compression. During compression, FLAC does not lose quality from the audio stream, as lossy compression formats such as MP3, AAC, and Vorbis do. FLAC reduces bandwidth and storage requirements without sacrificing the integrity of the audio source. A digital audio recording (such as a CD track) encoded to FLAC can be decompressed into an identical copy of the audio data. Audio sources encoded to FLAC are typically reduced in size 40 to 50 percent (46% according to their own comparison).

What is DRM?

Digital rights management (DRM) is a generic term that refers to access control technologies used by hardware manufacturers, publishers, and copyright holders to limit usage of digital media or devices. The lack of DRM has several benefits for you as a customer: You can burn a copy of your download onto CD-R or DVD-R You can play your download using your media player You can transfer your download to your portable device

Why do you burn CD?

AAD Master CD is superior to stamped CD in two main respects: BLER is about 100 times lower; there is only one generation of transfer instead of up to five.

What is the problem with a stamped CD?

Unfortunately, once a master CD is sent to a replication plant for production, the quality is slipping out of our control. The stamped CD is always inferior to the master. The engineer has no control over the jitter and block error rates during the replication process. Three, often up to five generations of transfer, are made from the original master to the glass stamper.

Master Tape

Why do you sell master tapes?

Master tapes present a more natural, a more dimensional, deeper and far more realistic sound, with unmatched airy ambience and detail, even when compared to the best LPs or SACD or other digital formats. Remember that he original recording was made on tape if you listen to an LP record.. Thus any other format is a serious manipulation of the original musical recording.

What type of tape recorder do you recommend to play the master tape?

You need a very good tape recorder which is able to play back half track 1/4" 15 ips tapes using 26.5" spool or pancake. Most of the professional studio tape recorder will suit you.

Why is your master tape so expensive?
