But I'm not sure if the parameters I write are right, whatever I write as parameters never gives me an error, so I can't tell if I'm right: the string is this: <code>gst-launch-1.0 -v filesrc location="$file" ! decodebin ! audioconvert ! audioresample ! audio/x-raw, format=S24LE,rate=176400,dithering=tpdf_hf,dithering-threshold=24,noise-shaping=high,quality=10,resample-method=blackman-nuttall,sinc-filter-interpolation=linear,sinc-filter-mode=full ! alsasink device=hw:1,0</code> <code></code>If I change the string to: <code>gst-launch-1.0 -v filesrc location="$file" ! decodebin ! audioconvert ! audioresample ! audio/x-raw, format=S24LE,rate=176400,xxxx=xxxx,xxxx=xx,xxxx=xxxx,xxxxx=xxx,resample-method=xxxxx,sinc-filter-interpolation=xxxx,sinc-filter-mode=xxxxx ! alsasink device=hw:1,0</code> still works! how do i know that i write the parameter names correctly? and if they are passed? <hr width="100%" size="2"> This is debugging: <pre class="code highlight" lang="plaintext">gst-launch-1.0 --gst-debug=audio-*:5, filesrc location="/var/lib/mpd/music/NAS/loss4/Nina Simone/Baltimore/1.
