1. Digital audio recording Kimmo Tukiainen

2. My background playing music since I was five first time in a studio at fourteen recording on my own for six months

3. Topics Basics of sound Recording equipment Workflow Software overview

4. Basics of sound

5. Sound is a mechanical wave

6. Wavelength, amplitude and frequency

7. Audible range Human: 20 - 20,000 Hz Bat: 100 - 100,000 Hz Dog: 10 - 35,000 Hz Elephant: 1 - 20,000 Hz Frog: 100 - 2,500 Hz

8. 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.

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

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

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

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

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

14. Inputs line microphone MIDI phono

15. Workflow

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

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

18. Publishing –File format, (file)compression

19. Logic Audio

22. Track automation

23. Sound quality issues noise clipping equipment (microphones, converters)

24. Q & A
