The EventSource API

The EventSource interface is used to receive server-sent events. It connects to a server over HTTP and receives events in text/event-stream format without closing the connection.

https://developer.mozilla.org/en-US/docs/Web/API/EventSource

Last-Event-ID

Setting an ID lets the browser keep track of the last event fired so that if, the connection to the server is dropped, a special HTTP header (Last-Event-ID) is set with the new request.

You take a stream/buffer of binary data. The start of your data is a "Page", which has a header followed by data.

Header

You need to read the following data from the header (see https://xiph.org/ogg/doc/framing.html for more detail)

• capture_pattern - bytes 0 to 3, must read OggS
• stream_structure_version - byte 4, must be 0
• header_type_flag - byte 5, a bitflag that tells you metadata about the page (is it a new packet? is a packet continued here? is it the first/last page of the stream?)
• absolute granule position - bytes 6 to 13, not needed unless you want seeking
• stream serial number - bytes 14 to 17, a serial number given to each stream contained in the Ogg file. This is important for playing Ogg files that contain other streams, such as video or cover art. You need to identify and only bother parsing the Opus stream.

Update

If you're OK in having a node-esm executable, please consider this solution.

#!/usr/bin/env sh
# the /usr/local/bin/node-esm executable
input_file=$1
shift
exec node --input-type=module - $@ <$input_file

How to record multiple applications and microphone into one audio file on Linux

Step 0. Terminology

Sinks are for output, sources are for input. To stream source to sink a loopback must be created. More shall you find there.

Step 1. Create output sink that will be recorded

Our output sink will be named recording.
