const TInt KA3FModeMonoValue

const TInt

KA3FModeMonoValue

Mode setting available.

"Mode" in this context refers to the number of channels (i.e. mono or stereo). The modes are given as UIDs. Mono data

const TInt KUidGainSawToothValue

const TInt

KUidGainSawToothValue

KGainSawTooth an explicit 0->aGain sweep, rising linearly. If the channel is active, the effective gain drops to 0 ASAP after the request. If used when the stream is not in EActive state, this acts as fade-in during the subsequent Activate() transistion.

const TInt KUidGainFadeOutValue

const TInt

KUidGainFadeOutValue

KGainFadeOut drop from current to 0, dropping linearly over aRampDuration period.

const TInt KUidGainRampedValue

const TInt

KUidGainRampedValue

KGainRamped (gradual) change from current gain values to those given in aGain over aRampDuration period

KUidGainRamped

const TInt KUidGainContinueValue

const TInt

KUidGainContinueValue

KGainContinue if a previous ramped operation is in progress, this continues but the concept of target gain is updated using the new values. aRampDuration is ignored the previous ramp duration is reused, minus the time already spent ramping. The smoothness of this operation will depend on the implementation. If no ramped operation is in progress, this is the same as KNullUid. This is intended as a way of changing gain values without stopping an ongoing ramp operation.
