fir2vsdsp.m content

Post by winwan »

I want to make an EQ driver. When I consult the VSIDE_DSP_LIB document, I see the following content, indicating that 32BIT is not supported at present. If 32BIT is supported, ir2vsdsp.m needs to be updated, right

Code: Select all

8.1 fir2vsdsp.m
B_ROUNDED = fir2vsdsp(B, BITS, UPSAMPLEBY, DOWNSAMPLEBY,...);
Parameters:
• B - Fir filter
• BITS - Number of bits. Currently only 16 is supported.
• UPSAMPLEBY - How many times to upsample before filtering
• DOWNSAMPLEBY - How many times to downsample after filtering

Hello!

At the moment, only 16 bits is supported.

However, for your particular need, we already have a high-quality equalizer driver available, called FtEqu. Have you tried it?

Kind regards,

Are you talking about FTOEQU? If it is, I have been using it, and I still look forward to supporting 32BIT
