<p>You are using different sound system in both recordings, even though both might use the same</p>
<p>phsyical device, ther eis a difference between pulse and alsa.</p>
<p> </p>
<p>try to adjust the alsasrc capture volume, you can use alsamixer for that.</p>
<p>select F6 to select your sound device, then F4 for the capture settings</p>

<div dir="ltr">Hi!
<div>I m discovering gstreamer to record audio and I got an issue. I m looking for an explication.</div>
<div>I tried a test</div>
<div>gst-launch -e pulsesrc device="alsa_input.usb-Samson_Technologies_Samson_UB1-00-UB1.analog-stereo" ! audioconvert ! audioresample ! pulsesink device="alsa_output.pci-0000_00_04.0.analog-stereo"</div>
<div>and it works very well, good sound in the headphone</div>
<div>but</div>
<div>
<div>gst-launch -e alsasrc device="alsa_input.usb-Samson_Technologies_Samson_UB1-00-UB1" ! queue ! audioconvert ! \</div>
<div>ffenc_ac3 ! filesink location=audio.mp3</div>
<div>the mp3 is not audible, the sound comes from far far far distance as the mic was not amplified.</div>
<div>I tried to modify the settings through the gnome sound applet, alsamixer, pavucontrol without result</div>
<div>What I do not understand in the pipeline concept ?</div>
<div>
<div>I work with a debian sid.</div>
<div>
<div>$gst-launch --version</div>
