1

Standing wave formula

1130/2(L)

2

magnetization of tape and the record head

the record head alters magnetic polarization of tiny particles - align magnetic domain with imposed field

3

Track formats

2 4 8 16 24

4

what is 2 track for?

final stereo mix

5

8, 16, 24 is for

multi-track recording

6

basic buttons on tape transport

record, play, stop, rewind, fast-forward

7

how to record ready a traditional ATR?

select track under "Ready" and press record and play together

8

how to record read a newer ATR

select track under "Ready" and hit record

9

3 magnetic tape heads

record head records
reproduce head playback
erase head

10

3 monitoring modes

input monitoring
reproduce mode
select synchronization

11

common tape speeds

7.5, 15, 30

12

effects of print-through

audio seeps through tape because it wasn't stored properly

13

how to prevent print-through

tails-out storage, where backing is on top, oxidized (data storing part is below)

14

how wide was tape

quarter inch to 2 inches

15

ATR signal flow now

mic to tape machine to DAW

16

disadvantages

punches had to be super precise and well-rehearsed, cutting and pasting is difficult

17

ATR

analog tape recorder

18

3 ways to reduce leakage

build massive, solid structure
eliminate joints, which easily transmit sound through barrier
dampen structures so walls are reinforced

19

what is leakage

resonance and sound from elsewhere

20

what is a soffit

cavity on front-facing wall in control room to mount monitors to wall to reduce reflections and resonances in control room

21

common practice for isolating floor-related noise

hockey puck iso mounts, or U-Boat float floats, or continuous underlay like rubber floor mat

22

why use double doors?

they form acoustical sound lock, reduces leakage because of air between the 2 solid barriers

23

what is an iso booth?

iso-room acoustically isolated/sealed area built to keep the louder instruments from the softer instruments

24

gobo?

acoustic partition, provides on-the-spot barriers to sound leakage

25

symmetry in control room and the sweet spot

the sweet spot is within the equilateral triangle, your ears must be equidistant to the speakers

26

standing waves also called

room nodes

27

standing waves are from

parallel walls

28

standing wave is

when sound wave is reflected and travels back on its own path, causing phase differences which interfere with the room's frequency response

29

magnetization and the erase head

high magnitude, high frequency AC current erases previous recorded signal

30

reproduce head

converts magnet pattern on tape to electrical signal
