audio from microphone to aac file is not working

[pumba]

I've tried to create an .aac audio file using gstreamer. Here's my code for it:
gst-launch-1.0 autoaudiosrc ! audioconvert ! voaacenc ! filesink location=file.aac

It does creates a file with that name, but that file is not playable.

when I replace the voaacenc element with lamemp3enc to create an mp3 file, it works.

now, what should I do to create an .aac file from microphone input ?

Hi,

Raw AAC data cannot be played. You need to either mux it into a
container or convert to ADTS:

gst-launch-1.0 autoaudiosrc ! audioconvert ! voaacenc !
"audio/mpeg,stream-format=adts" ! filesink location=file.aac

In more complicated pipelines, you might want to add an aacparse
element after voaacenc.

have you tried running this code in terminal ? I'm getting no sound while playing in vlc.

I've solved the problem to an extend, here's the pipeline:

gst-launch-1.0 alsasrc ! "audio/x-raw,channels=2,rate=48000,format=S16LE" ! audioconvert ! "audio/x-raw,channels=2,rate=48000,format=S16LE" ! voaacenc ! "audio/mpeg,stream-format=adts,channels=2,rate=48000"  ! filesink location=goo.aac

still some random noise is there.
