Recording musical disk

Similarly, when we listen to music through a speaker, what we hear is the original music, distorted by its passage through whatever recording device (microphone + amplifier), storing device (such as tape, casette, record, compact disk), and audio reproduction system (amplifier, speaker) is used. More precisely, what we hear is the convolution of the original music and the instrumental response. 

CD-V (compact disk-video) is premolded for both video and digital music 0 = 305 mm oi0 = 203 mm. There is also a videocHp version (0 = 120 mm) for 22 min CD audio and 5 min of video information. CD-VEP (video extended play) 0 = 200 mm, is recorded on both sides, whereas for CD-VLP (video long play) 0 = 200 mm, one- or two-sided recording can be selected max. 60 min video/side. 

Post-production Sound Editing In the context of sound recording, the ability to correct the pitch of an off-key musical note can help salvage a take that would otherwise be unusable. Multi-track hard-disk recording machines often offer such capabilities. 

The first CD standard, called the Red Book standard, is the standard for recording digital audio (audio CDs that you play in your home CD player). It specifies the recording level as 16-bit, 44.1 KHz, and that the entire disk will have an index of the music tracks stored on it. The Yellow Book standard defines the main requirements for data storage on a CD-ROM. This standard supports both PC (ISO9660) and Mac (HFS) file system formats as well as file system formats from other vendors (DEC and VMS). 

A large variety of thermoplastics are molded using the injection molding process. Some products, such as disks for (analogue) music records, are molded laiNSmpressio ifMiiyiecttoa Coin ssion molds, while(digital)compa are injection molded. 

The main difficulty in using optical fiber probes is associated with their proper calibration. For solids velocity measurements Ohki and Shirai (1976) calibrated their probe (cf. Table 5) by dipping its top, about 2 mm, into a thin bed of the same material placed on a rotating disk (a music record disk player was used) and obtained a cross-correlation of the signals received from two fibers. The cross-correlation can be successfully applied for the analysis of velocity data unless the velocity fluctuates too often.
