https://github.com/TaylorSMarks/playsound/issues/101
(A workaround exists: downgrading to version 1.2.2, but that comes with its own issues.)
The last time I experimented with audio in Python, I was surprised by how lacking its multimedia libraries are.
For example, when I needed to read audio files as data, I tried `SoundFile`, `librosa` (a wrapper around `SoundFile` or `audioread`), and `pydub`, and none of them was particularly satisfying or has seen much active development lately.
If you need to read various formats, pydub is probably your best bet (it does this by invoking ffmpeg under the hood). I was hoping for a more "native" solution, but oh well. Unfortunately, `pydub` is also unmaintained and has some serious performance issues (for example: https://github.com/jiaaro/pydub/issues/518 )

Project mention: Can't pay, won't pay: streaming services are driving viewers back to piracy | news.ycombinator.com | 2025-08-14
I developed a tool (https://github.com/smacke/ffsubsync) which can sync subtitles against each other, and this can be used in conjunction with other tools such as https://pypi.org/project/srt/ to combine multiple subtitle streams into a single stream. I've used this strategy to good effect to get both English and Chinese subtitles up at once.

Project mention: Show HN: Shoggoth Mini – A weird tentacle robot powered by GPT-4o and RL | news.ycombinator.com | 2025-07-15
> also, "GPT-4o continuously listens to speech through the audio stream," is going to be problematic
Seems like openWakeWord or porcupine could be able to solve by adding a layer for wake word detection before sending the prompt off.
I wonder if latency would be any better with a local model cached in a 16GB or 24GB graphics card. It would have to be a quantized/distilled model, but maybe performance would still be acceptable.

picard
A cross-platform music tagger powered by the MusicBrainz database. Picard organizes your music collection by updating your tags, renaming your files, and sorting them into a folder structure, exactly the way you want it.
If you have the files downloaded, picard is also useful - https://picard.musicbrainz.org/

Project mention: Benn Jordan's AI poison pill and the weird world of adversarial noise | news.ycombinator.com | 2025-04-15
https://github.com/riffusion/riffusion-hobby
The more advanced music generators out now I believe have more of a 'stems' approach and a larger processing pipeline to increase fidelity and add tracking vocal capability but the underlying idea is the same.
Any adversarial attack to hide information in the spectrograph to fool the model into categorizing the track as something it is not isn't different than the image adversarial attacks which have been found to have ways to be mitigated.
Various forms of filtering for inaudible spectral information coupled with methods that destroy and re-synthesize/randomize phase information would likely break this poisoning attack.
