    Project mention: Show HN: CompressX, my FFmpeg wrapper for macOS, made $9k in the last 4 months | | 2024-04-10


    Since FFmpeg is GPL2, doesn’t that require CompressX to disclose its source code?

    IANAL, apologies if I miss understand license requirements.

    Project mention: Amazon plans to charge for Alexa in June–unless internal conflict delays revamp | | 2024-01-20

    Yeah, whisper is the closest thing we have, but even it requires more processing power than is present in most of these edge devices in order to feel smooth. I've started a voice interface project on a Raspberry Pi 4, and it takes about 3 seconds to produce a result. That's impressive, but not fast enough for Alexa.

    From what I gather a Pi 5 can do it in 1.5 seconds, which is closer, so I suspect it's only a matter of time before we do have fully local STT running directly on speakers.

    > Probably anathema to the space, but if the devices leaned into the ~five tasks people use them for (timers, weather, todo list?) could probably tighten up the AI models to be more accurate and/or resource efficient.

    Yes, this is the approach taken by a lot of streaming STT systems, like Kaldi [0]. Rather than use a fully capable model, you train a specialized one that knows what kinds of things people are likely to say to it.


  • BlackHole

    BlackHole is a modern macOS audio loopback driver that allows applications to pass audio to other applications with zero additional latency.

    Project mention: Use Tonex software to RIP Amplitube Tones without Hardware. | /r/AmpliTube | 2023-12-10

    Project mention: Show HN: Synced lyrics database with a free, easy-to-use API | | 2024-02-23

    I was always frustrated that there is no solid source for synced lyrics that also offers decent API support. There is good ol' Crintsoft's MiniLyrics that is thankfully free software, was what I used a lot in my childhood, but unfortunately the API is highly obfuscated. Another popular choice is the Musixmatch API, which has a very large database of synced lyrics, but with "free" API that are reverse-engineered from their app, you will quickly run into rate-limit.

    That's why I created LRCLIB. It's aimed to provide completely free synchronized lyrics for everyone, especially for FOSS music players, with zero profit intention. It currently has nearly 3,000,000 (not deduplicated) lyrics in database. You can also contribute to the database by adding and syncing lyrics for your favorite songs using the LRCGET client.

    I'm trying my best to make LRCLIB server-side code open-source as soon as possible. But right now, full LRCLIB's database dumps have already been uploaded regularly and publicly, which are simply sqlite3 files. Feel free to download, look at or do anything you want with the database at

    Many open-source projects have already begun integrating LRCLIB, including:
