@HelveticAlex, I have tried to enable support for other codecs on Nora.
But the main problem is that chromium only comes with a handful of audio codecs to work with and I have no idea how to integrate more codecs to it.
Chromium should support Opus (and Vorbis). They themselves popularized this audio codec. Now as for the implementation, unfortunately I don't know either... but I do know that it's possible given that it's "built-in"!
Since it's an electron-based app, it should even have opus enabled by default.
<audio controls>
<source src="path_to_audio_file.ogg" type="audio/ogg; codecs=opus">
Your browser does not support the audio element.
</audio>
For Advanced Processing, like using an EQ or something, the Web Audio API should be enough. Opus uses "AudioContext" to decode it's thing.
async function playOpusAudio(audioUrl: string) {
const audioContext = new AudioContext();
const response = await fetch(audioUrl);
const arrayBuffer = await response.arrayBuffer();
const audioBuffer = await audioContext.decodeAudioData(arrayBuffer);
const source = audioContext.createBufferSource();
source.buffer = audioBuffer;
source.connect(audioContext.destination);
source.start();
}

((Example in TypeScript, DO NOT COPY, it probably won't work with the structure of this app))
@HelveticAlex, It does work. But it won't support metadata editing because the package I'm using only supports mp3.
Mhmm, what about https://www.npmjs.com/package/music-metadata-browser ?
It requires a little more work, but given the number of metadata supported, it could be incredible for Nora !

I'm already using its nodejs implementation and it only supports reading metadata.
Until finding a solution for editing the metadata, simply implementing the codec is enough (at least for my case) (and if I need to change the metadata of any files, I'll just do it with Mp3tag).
It would be a pleasure to deliver this patch as soon as possible (or the next one) !
Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs.
Is your feature request related to a problem? Please describe. As .OPUS is becoming increasingly relevant and serves as a direct replacement for .MP3, its absence limits the usability of the platform for users who prefer or require .OPUS for its superior efficiency and quality.
Describe the solution you'd like I would like Nora to implement support for the .OPUS audio codec..
Describe alternatives you've considered An alternative solution could be continuing to convert .OPUS files to other supported formats like .MP3 or .AAC, but this results in a loss of quality and/or increased file sizes, which is not ideal. Native .OPUS support would be a much more efficient and quality-preserving option.
Additional context Adding .OPUS support could also align Nora with modern audio standards and practices, as more devices and platforms are beginning to adopt .OPUS due to its advantages over other audio formats. This enhancement would not only improve functionality but also future-proof the platform as media standards evolve.
