Page 56: Appendix C: An Introduction To Digital Recording
Appendix C: An Introduction to Digital Recording Appendix C: An Introduction to Digital Recording Converting Sound into Numbers In a digital recording system, sound is represented as a series of numbers, with each number representing the voltage, or amplitude, of a sound wave at a particular moment in time. - Page 57 Appendix C: An Introduction to Digital Recording Each digit in the number is called a bit. The binary numbers expressed in Figure A are sixteen bits long, and have a maximum value of 65,535. The more bits that are used to store the sampled value, the more closely it will represent the source signal. In a 16-bit system, there are 65,535 possible combinations of zeroes and ones;...
- Page 58 Appendix C: An Introduction to Digital Recording Also important to the quality of a digital recording is the frequency with which the samples are stored, called the sample rate. In order for a waveform to be faithfully digitized, it must be sampled at a minimum of twice the highest frequency to be stored.
- Page 59 Appendix C: An Introduction to Digital Recording level of analog audio signals. The most common are dBu and dBV decibels. Both of these represent voltage levels and still double for every increase of 6dB. It is only the reference point, or 0dB level that is different. A 0dBV signal has a voltage level of 1.0 volts.
- Page 60 Appendix C: An Introduction to Digital Recording The above nominal levels represent typical or average levels that are often exceeded when recording loud signals such as drum beats. The difference between the nominal level and the loudest signal that can be recorded without clipping is called “headroom”.
- Page 61 Appendix C: An Introduction to Digital Recording are matched, any noise added to the minus component will still be approximately the same as that picked up by the plus component and will be subtracted out by the input amplifier. Your Echo product uses this type of output. Balanced signals connect with either XLR connectors or TRS (tip, ring, sleeve) connectors.
- Page 62 Appendix C: An Introduction to Digital Recording read these levels, the low noise requirements of the surrounding circuitry such as power supplies and amplifiers would be so stringent that they would either be impossible or too expensive to build. In answering the second question, consider the fact that music is often compressed or amplified after it is recorded, and that some headroom is necessary when recording to avoid clipping.
