The DC-Graphic EQ filter is a 31 band graphic equalizer for MS DirectShow. The frequency table is a slightly modified ISO table to prevent overlapping. The filter will work on 8, 16, 24, 32 bit integer as well as on 32 bit floating point buffers. The internal DSP is done in 32 Bit floating point and has been optimized using SSE and SSE3 instructions. The filter is also setup to connect to SPDIF and DTS types in case you are playing around with AC3 filter. This will prevent the typical "cannot connect pins" Error. However, in DTS/SPDIF mode, the audio data will be bypassed and not modified.
Many thanks to Jose F. Martinez Antonini for calculating the table, suggestions and beta testing.
Installation
You can use the installer zip. This will install and uninstall the filter automatically.
