type

One of the following types of effect.

BASS_FX_DX8_CHORUS	DX8 Chorus. Use BASS_DX8_CHORUS structure to set/get parameters.
BASS_FX_DX8_COMPRESSOR	DX8 Compression. Use BASS_DX8_COMPRESSOR structure to set/get parameters.
BASS_FX_DX8_DISTORTION	DX8 Distortion. Use BASS_DX8_DISTORTION structure to set/get parameters.
BASS_FX_DX8_ECHO	DX8 Echo. Use BASS_DX8_ECHO structure to set/get parameters.
BASS_FX_DX8_FLANGER	DX8 Flanger. Use BASS_DX8_FLANGER structure to set/get parameters.
BASS_FX_DX8_GARGLE	DX8 Gargle. Use BASS_DX8_GARGLE structure to set/get parameters.
BASS_FX_DX8_I3DL2REVERB	DX8 I3DL2 (Interactive 3D Audio Level 2) reverb. Use BASS_DX8_I3DL2REVERB structure to set/get parameters.
BASS_FX_DX8_PARAMEQ	DX8 Parametric equalizer. Use BASS_DX8_PARAMEQ structure to set/get parameters.
BASS_FX_DX8_REVERB	DX8 Reverb. Use BASS_DX8_REVERB structure to set/get parameters.
BASS_FX_VOLUME	Volume level adjustment. Use BASS_FX_VOLUME_PARAM structure to set/get parameters.

other effects may be supported by add-ons, eg. BASS_FX.

priority

The priority of the new FX, which determines its position in the DSP chain. DSP/FX with higher priority are applied before those with lower. This parameter has no effect with DX8 effects when the "with FX flag" DX8 effect implementation is used.

Return value

If successful, then the new effect's handle is returned, else 0 is returned. Use BASS_ErrorGetCode to get the error code.

Error codes

BASS_ERROR_HANDLE	handle is not a valid channel.
BASS_ERROR_ILLTYPE	type is invalid.
BASS_ERROR_NOFX	The specified DX8 effect is unavailable.
BASS_ERROR_FORMAT	The channel's format is not supported by the effect.
BASS_ERROR_UNKNOWN	Some other mystery problem!

Remarks

Multiple effects may be used per channel. Use BASS_ChannelRemoveFX to remove an effect. Use BASS_FXSetParameters to set an effect's parameters. An effect's priority value can be changed via BASS_FXSetPriority.

Effects can be applied to MOD musics and streams, but not samples. If you want to apply an effect to a sample, you could use a stream instead.

Platform-specific

DX8 effects are a Windows feature requiring DirectX 8, or DirectX 9 for floating-point support. On other platforms, they are emulated by BASS, except for the following which are currently unsupported: COMPRESSOR, GARGLE, and I3DL2REVERB.
