Raita 1a. Voice announcement by George Cardas, ”Greetings from the left channel”
Spiral
Raita 1b. Voice announcement by George Cardas, ”From the right channel”
Spiral
Raita 1c. Voice announcement by George Cardas, ”From both channels” Note: This is lateral modulation (mono, in phase).
Spiral
Raita 1d. ”In polarity” Both channels in positive polarity
Spiral
Raita 1e. ”Out of polarity” Both channels in reversed or negative polarity Spiral
Raita 1f. 13 strikes on a high ”B-flat” on a piano Note: The last of the 3 strings are brought into zero-beat, dead-on tuning. Listen for the impact of hammer on string, quickly followed by room reflections mingling with one another, followed by a keener sense of the piano sound itself, as the ring-out time of the string exceeds that of the reverb time of the room.
Spiral
Raita 1g. Hollow sticks, of various lengths and diameters, being struck, one on another. Note: It is recorded in a very reverberant, spacious environment. The spatial, impact and directional cues will not sound correct if the polarity is wrong.

Lock-out. Note: The remainder of this side is cut at 22.5 rpm and consists of three wide bands of pink noise, separated by two blank, 1/2 inch wide plateaus. The plateaus are protected by two blank grooves on each side, to keep the stylus from sliding into the pink noise. The three wide bands are groups of individually locked grooves of mono pink noise, recorded at ”0” dB, relative to NAB standard level. These are continuous grooves and the stylus will stay in a groove until it is lifted out. This 180 gram pressing is made of specially formulated hard vinyl.

Raita 2. 20 locked grooves, lateral modulation (mono)
1/2” wide, unmodulated plateau
Raita 3. 32 locked grooves, vertical modulation (out-of phase)
1/2” wide, unmodulated plateau
Raita 4. 20 locked grooves, lateral modulation (mono)
Raita 5. 26 unmodulated grooves Note: These unmodulated grooves facilitate electro-forming (matrix) operations and help vinyl flow in the record press, for a quieter, flatter disk.
