Can I shrink the DSP/SRC's heap memory?

[jens6151 0 1 1]

At DSP Install it says that SRC is 21 kB binary size.

Image     Used memory       Binary size
SRC       128 kbyte         21 kbyte

I am using only Mono input experimenting with small memory tiles configuration.
Unfortunately the required size is 73kB (75208 bytes), slightly above one small tile of 64kB

printf("loadinfo: size is %d\n", loadinfo->textsize + loadinfo->datasize);

Can I somehow shrink the SRC program? Like to reduce the heap a little bit?

Hi, @jens6151-0-1-1

I don't think you can shrink the SRC program.
But let me do some investigation and get back to you.

[jens6151 0 1 1]

@CamilaSouza Thank you for checking. In the meantime, I will try 48 kHz which does not need the SRC.
The reason is that I am out of memory. So I need to save memory where possible. 128 kB for sampling rate conversion is too large for my case.

@jens6151-0-1-1 Using 48 KHz without doing any sampling conversion works fine for me. I do not need to load any DSP and do not need ASMP.
