It's still an early Version

Obsidian Recorder Plus

This plugin provide a better recorder in Obsidian

• just record, you could pause and stop
• more than record, with configs and more

Features

• from native WebAPI feature, clean and save:
  • use audioContext as Method, NO MORE BitRate limit! (s.Issue #1, still debugging...)
  • adopt newest WebCodecs as encoder, your Recording has correct and accurate duration info now (which means SEEKABLE)!
• open in Obsidian's sidebar with more control options (PC: with hover editor you could also hover it.)
• more than native recorder, you could configure the quality, could CONTROL the recording (e.g. pause, resume, set timeout..)
• rename and save to other places as wish
• encode type & file type as wish
• (upcoming) multi-platform
• (upcoming) pin timestamps while recording

Supported Codecs/File Formats:

• aac/m4a
• opus&vorbis/webM
• pcm/wav (working on it...)
• flac/flac (upcoming)

Reference & Note

• Recorder:
  • common method: https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder
  • method adopted here:
    • WebCodecs
    • AudioContext: https://developer.mozilla.org/en-US/docs/Web/API/AudioContext
• webM, which is a strict mode of matroska:
  • codec: https://www.matroska.org/technical/codec_specs.html
• packaging: https://github.com/davedoesdev/webm-muxer.js, https://github.com/Vanilagy/webm-muxer
• I am not sure if it is the limit of Electron. bitRate is max. 300Kb/s when using inner Encoder of any kind. I am trying hard to figure it out. For now, the only way to break this limit is directly reach AudioContext and get the stream either from audioWorklet or create a MediaStreamTrackProcessor, which I am still working on.
