(4.08) DSP options and plugins

DSP options

The response speed to all these options is dependant on the buffer size, the delay will be the length of the buffer chosen in the device setup.

  • Amplification slider - This is different to the volume slider. The volume slider controls the level of the sound card output, the amplification slider controls the level of the actual decoding. The higher the amplification, the greater the dynamic range of the decoding output, but if it's too high clipping may occur resulting in distortion of the sound.
  • Auto-amp - This causes the amplification level to be automatically reduced whenever clipping occurs. With fade-in enabled, it will fade-in new tracks until they clip, then it'll behave the same as normal. Dynamic mode continues to increase and decrease the amplification level throughout playback.
  • Reset on new track - Resets the amp level when a track is loaded.
  • Replaygain - When a track has "replaygain" information, XMPlay can use it for the default amp level. XMPlay can read RG information from OGG files and APEv2 and ID3v2 tags. Native plugins may also support it, but Winamp plugins have no way of communicating that information. When a track doesn't have the preferred value but does have the other (eg. "Album" is chosen but only "Track" is available), it'll be used instead.

The bottom part of the window is dedicated to DSP plugins. The "up" and "down" buttons can be used to change the order in which the DSP are applied. This DSP list also allows for multiple DSPs to be active at once, in whatever order the user chooses. There are 2 built in DSPs - the equalizer and reverb. Most Winamp DSP plugins can be used via the "Winamp DSP wrapper". You can create your own plugins by using the SDK available from the XMPlay website.

How to set up a DSP

Once a DSP plugin has been installed it then has to be setup within XMPlay. In this example we will be setting up the iZotope Ozone DSP.

  1. Once installation is complete, start XMPlay and proceed to the Options dialog. Under the DSP option you will find the Winamp DSP wrapper listed, press Add and double click the new "Winamp DSP wrapper - no plugin" entry.

  2. The DSP wrapper's config will appear, once the iZotope Ozone plugin is selected Ozone's Dialog will appear, and may be enabled to process audio via the check box in the same dialog.

    Tip: Most DSP plugins need the Resolution left at 16 bit. It is also recommended that you are not playing music during the DSP setup.

  3. The Ozone DSP will now be functioning with XMPlay. Close the DSP Wrapper's Configuration window to continue.
