QUESTION
I'm looking at two audio channels: SendAudio and ReceiveAudio coming from a WebRTC call. For each respectively, we can see the following metrics:
ANSWER
Answered 2020-Mar-24 at 20:17PacketsLost is not included in the packetsReceived, but included in packetsSent. PacketsSent = packetsReceived + packetsLost + packetsDuplicated. PacketsDuplicated will be discarded by the receiver. So I suppose you want to calculate audio quality based on the packets loss, I think you should use bit rate as audio quality.
QUESTION
I have a c program which uses 2 threads. Now I would like to call in both threads a Python function. When I only call one python function in one thread it does work, but when calling in both of them at the same time it gives this error:
Fatal Python error: GC object already tracked.
When looking around I found this is caused by the python-functions and that the Garbage Collector does not differentiate between both. Now I can't seem to find any examples regarding this topic. I did find some clues which could help but again no example on how to implement them. I think I need to let the GC know the difference between both in a way similar to a malloc().
I thought i could use the following function PyObject_GC_New(), but I don't know how to implement this.
Beneath my code, which works when you comment out the audioSend() in speakerPlay() and replace it with a print statement for example.

Answered 2020-Mar-17 at 14:03Python protects its object space against concurrent access via a global lock, appropriately called the "Global Interpreter Lock". You need to respect and accommodate that in order to use the same embedded Python interpreter from multiple threads of the host C program. The documentation contains a section describing these requirements. There are ways to take fine-grained control of all of that, but, per the docs,
[t]he typical idiom for calling into Python from a C thread is:
QUESTION
As a proof-of-concept I need to create a HTTP server which on GET request should start continuous stream of non-encoded/non-compressed audio data - WAV, PCM16. Let's assume the audio data are chunks of 4096 randomly generated mono audio samples @44.1kHz sampling rate.
What should I put in the HTTP response header in order to browser on the other end start a player in its UI for the user to listen in realtime?
I was reading about "Transfer-Encoding: chunked", "multipart", mimetype="audio/xwav", but still not sute what and how to use...
Great would be if someone can give me an exact example on Python/Flask because I'm not so confident with the web development.
PS1: Replacing HTTP server with an embedded device with limited HW power will be the next stage after the PoC.
PS2: This is the code which actually works and sends an WAV chunk as a single HTTP response:

Answered 2019-Nov-28 at 09:30Server-side Streaming TechnologiesIn order to stream live audio, you will need to run specific streaming software on your server.
SHOUTcast
SHOUTcast is a cross-platform proprietary technology for streaming media. Developed by Nullsoft, it allows digital audio content in MP3 or AAC format to be broadcast. For web use, SHOUTcast streams are transmitted over HTTP.
Note: SHOUTcast URLs may require a semi-colon to be appended to them.
Icecast
The Icecast server is an open source technology for streaming media. Maintained by the Xiph.org Foundation, it streams Ogg Vorbis/Theora as well as MP3 and AAC format via the SHOUTcast protocol.
Note: SHOUTcast and Icecast are among the most established and popular technologies, but there are many more streaming media systems available.
Edit
I'm a Django guy and I've been testing things, and, seems, it works fine, only needs some proper file management and stuff. I've been working with mp3, but you can work with anything browsers have support for.
