Newby Wants Help With Settings

[AnnieBody]

Hi
Currently use Logitech Squeezebox with wav convolution file.
I want to try the same file on my Cambridge Audio streamer rather than stream via the Squeezebox, which I intend to phase out, and am getting lost!
The Squeezbox is simple: install addon, select option, then done!

1. Just want to try with 16bit 44.1KHz flac file for now, so set:
stream transcode: flac:wav;

2. I have ffmpeg installed and used elsewhere by various other programs. As these all seem to want their own install tied to them I followed the advice given by 'tgb' on another thread 'convolution filtering':
"According to few posts on forums, the basic ffmpeg in the Syno is "very basic".
Thus, I went there => https://synocommunity.com/package/ffmpeg
You download the right version according to the proc of your Syno => manual install => done."
Downloaded version 4.3.3-39 / 7.0 x86_64 for my Win 10 x64 pc.

3. Followed the instructions:
"On Windows, the full path to the opt/bin directory is
C:\Users\your-user-name\AppData\Roaming\MinimServer\opt\bin
The AppData directory is hidden by default in Windows Explorer and you can access it by typing this path in full into the Windows Explorer address bar."
Then created a 'bin/ffmpeg' sub-folder and placed the ffmpeg *.spk file into that.

4. Set:
stream converter: opt/bin/ffmpeg
I now get "Converter not installed..."

5. Followed the instructions:
"To enable convolution filtering, set the stream.options property to
convOut=-i filter-file-path -lavfi filter-chain
where filter-file-path is the fully-qualified absolute path for your convolution filter file and filter-chain is a filter chain containing afir followed optionally by any valid options supported by FFmpeg for the afir filter. For example, if you specify
convOut=-i /home/myuser/myfilter.wav -lavfi afir
FFmpeg uses the afir filter with the convolution file /home/myuser/myfilter.wav and no afir options.

6. Created a new sub-folder in the user bin folder:
opt/bin/convolution
then added a copy of my pre-made wav file '1impulse.wav'.

5. Set:
stream options: convOut=-i /bin/convolution/1impulse.wav
(I'll worry about options later)

So, from 4. above can anyone help to resolve the problem with the 'stream converter'?
Regards and thanks
