Hi, this video has 128kbps and 48kbps m4a audio formats:

 youtube-dl -F https://www.youtube.com/watch?v=dAIBDfzrzJk | egrep "Available|audio"
[info] Available formats for dAIBDfzrzJk:
139          m4a        audio only DASH audio   51k , m4a_dash container, mp4a.40.5@ 48k (22050Hz)
251          webm       audio only DASH audio  103k , webm_dash container, opus @160k (48000Hz)
140          m4a        audio only DASH audio  131k , m4a_dash container, mp4a.40.2@128k (44100Hz)

And that video has one m4a and 3 opus audio bit-rates :

250          webm       audio only DASH audio   73k , opus @ 70k, 51.83MiB
140          m4a        audio only DASH audio  137k , m4a_dash container, mp4a.40.2@128k, 109.30MiB
251          webm       audio only DASH audio  145k , opus @160k, 94.41MiB

48kb/s (for opus/aac) is enough for human voice speeches recordings, therefore it would be really great if you handled these smaller bitrates audio formats so one can download smaller audio files for long videos (from one upto 3 hours long for full video teachings) ?

Thanks again for this great app :-)

God bless you !

Hello,

I want to send my sincere thanks for this wonderful app that has improved my quality of life and that of several friends!

I've been so happy to see audio only downloading in opus format as a supported feature. I would like to second the above request and specifically request support for downloading in lower bitrates than the currently supported 50kbps.

The marvel of the technology in the opus format is that it is capable of producing perfectly acceptable compressions of human voice down to bitrates of 8-12kbps. This is potentially revolutionary for people who find themselves (as I have at times) in any one of the following situations:

• Living in a country such as the United States or Canada with unusually high costs for mobile data use

• Living in a country where wireless infrastructure is not well developed as has difficulty serving larger downloads

• Living in an isolated or rural area where internet is slow and/or spotty

• Using technology in settings such as remote research stations or wilderness areas where low data transmission rates are critical

Support for 50kbps compression is great, but I feel like there is a great case to be made to take advantage of Opus's industry-leading low bitrate performance. According to listening tests, Opus producing acceptable voice quality at 6-8kbps, exceeds telephone quality at 12kbps, and achieves near transparency at 24kbps. Those of us who need to download speech-based audio files with the current supported bitrates are using at least double the bandwidth necessary for high quality, and up to 4 times as much for acceptable quality audio.

Thanks again for all of the hard work that you are tirelessly doing in supporting this project!!

@redrubberball909 Newpipe can only extract those streams for a particular video that a service provides. It does not do any conversion of its own.

support for downloading in lower bitrates than the currently supported 50kbps.

Those 50 kbps streams are provided by Youtube. If it provides streams with a lower bitrate, Newpipe will show them automatically.

@opusforlife2 I was not asking for a conversion at the time I created this issue but maybe the title of my issue was a little confusing.
So I've just changed it.
Now we need to find youtube videos with very low opus bitrate to check if this issues has been already fixed or not.
