Use live audio

[jeroenboumans]

I'm looking for docs to use live audio stream as input for a BirdNET-Lite based application like the live stream demo:
https://birdnet.cornell.edu/live/

Is it possible to do this with the current setup as well?

I'm also interested in this topic.

This would be fine, also interested.

I was able to make Live Audio work as follows. Perhaps it is a naive approach but it seems robust.

• Create a script that records audio in 3 second clips and stashes them in a working directory. Only record up to a maximum number of clips eg. 2 files.
• Modify the analysis script to scan for files in the working directory - process the oldest file and then delete it.
• Run these scripts as separate processes. The recording script will fill the directory and the analyses script will empty it.

Analysing a 3s clip on a Raspberry Pi 4 only takes about 0.5s, so this scheme should never fall behind real-time (ignoring the 3s delay for sampling the audio)

Hello Stefan, Can you support us with the scripts via GitHub?

Hi @CoreProduction, hi @kahst
as i am also in the process of setting up a live stream analysis (and struggeling a bit) would you be so kind and share your scripts for live audio with us?
Also if anyone could give a walkthrough of setting up BirdNET on a Pi 4 this would be super nice!
Thanks and greetings!

I am also highly interested in a walk-trough (especially for the Tensorflow installation) for the Raspberry Pi 4.

To keep this issue reserved to the live audio input i am going to open a new issue relating to BirdNET and Tensorflow installation on the Raspberry Pi 4. Please comment there!

I also struggle with the Tensorflow installation ob Raspberry Pi 4...

@Christoph-Lauer: Please use the new issue i opened for the topic on installation. Instead of compiling yourself you could have used a precompiled bin from:
