Topics Basics of sound Recording equipment Workflow Software overview

Basics of sound

Sound is a mechanical wave

Wavelength, amplitude and frequency

Audible range Human: ,000 Hz Bat: ,000 Hz Dog: ,000 Hz Elephant: ,000 Hz Frog: ,500 Hz

Decibels (dB) and zero level One decibel is the amount by which the pressure of a pure sine wave of sound must be varied in order for the change to be detected by the average human ear. The decibel can express an actual level only when comparing with some definite reference level that is assumed to zero dB.

Sampling Makes a wave file (.wav) Mono or stereo Sample rate samples per second Bit depth How accurately values are defined

Sampling examples 44KHz 16-bit 44KHz 8-bit 22KHz 8-Bit 11KHz 8-bit

MIDI A standard for connecting electronic musical instruments to a computer and storing musical DATA describes the music (like XML) light files

Analog recording equipment sound source track on a tape preamp/mixer

Digital recording equipment sound source hard drive keyboard ad converter / sound card MIDI interface

Inputs line microphone MIDI phono

Workflow

Making a project –Sample rate / bit depth –Click settings Recording –Adjusting input level –MIDI and Wave –stereo or mono

Mixing –Volume, pan, effects –Placing sounds in the audio landscape –bouncing Mastering –Compressing –Equalizing –boosting the overall level by limiting or normalizing

Publishing –File format, (file)compression

Logic Audio

Track automation

Sound quality issues noise clipping equipment (microphones, converters)
