- All this VAMPS stuff/hype and several messages on comp.sys.amiga.audio,
- got me thinking about surround sound, etc, etc.
-
- One of the more interesting things I can across was changing the phase
- of stereo sound samples to create a pseudo 'surround sound' effect.
- (sheesh haven't we heard something like that before somewhere ;)
-
- Basically, by changing the phase of one channel by 180 degrees, one can
- 'broaden' the sound stage.
-
- You can try this yourself if you have an AudioAnimator with Version 1.2
- or 1.3 of the AE software, just record a mono-sample, paste it to a
- blank stereo-sample, and change the phase of 1 channel. You have to set
- the effects channel option to 'Display channel only' for it to really
- work.
-
- I sampled a fairly long sample and changed the phase of a large chunk in
- the middle of it, and there is a _noticeable_ difference.
-
- (BTW try listening to the sound via the internal speaker: when you
- listened to the modified chunk through it, the sound volume dramatically
- fades out, since both the channels effectively cancel each other out
- because of the opposing phases).
-
- Anyway, a suggestion: would it be easy to implement this sorta thing in
- a mod player or the next new way cool music program on the IIgs?
-
- (Basically ensure that the phase of the left channel is opposite to the
- right channel)
-
- soniqTracker / ModZap with 'pseudo surround sound' would be neat :)
-
-
- Awaiting with bated breath
