Primary domain change, back to hydrogenaudio.org

2025-04-29 14:54:07 by Peter | Views: 736 | Comments: 5

The hydrogenaud.io domain was originally registered as failsafe / temporary measure. We kept it for over a decade, while redirecting from original hydrogenaudio.org.
Today I have reverted this change - hydrogenaud.io now redirects to hydrogenaudio.org
Everything should work as before. No, I'm not getting rid of the .io domain, but I do not want geopolitics to possibly affect our operation, potentially causing someone totally not affiliated with us to take domain being linked from many places on the internet.

Expected Downtime: Server Moving

2025-04-23 21:01:55 by spoon | Views: 2314 | Comments: 1

The current data center in which Hydrogen audio (and all of dBpoweramp, and foobar2000, AccurateRip, etc) is closing in 4 weeks time. Today I installed new equipment in a new data center ready for the move. In about 1 weeks time, this forum will be locked and will take the existing server (with everything running well) over to the new datacenter and update the DNS. Downtime at worst will be 1 day.

[Update: HA is now in the new datacenter the board has been opened. ]

[OPEN SORUCE] SEA - Simple Embedded Audio Codec

2025-04-13 20:28:50 by forart.eu | Views: 1375 | Comments: 0

SEA is a low-complexity, lossy audio codec designed for embedded devices, inspired by the awesome QOA codec. Like QOA, SEA utilizes the Least Mean Squares Filter (LMS) algorithm, but it introduces variable bitrate (VBR) support and features slightly modified quantization tables. The reference implementation is written in Rust, and a compact ~250-line decoder written in C is also available for demonstration purposes.

You can test SEA in your browser here: https://daninet.github.io/sea-codec/

Key Features
  • Fast, low complexity, time-domain compression. The decoder fits into ~250 lines of C code.
  • Ideal for low-power embedded devices, game assets, and live streaming.
  • Flat frequency response: No low-pass filtering is applied, preserving the full frequency range.
  • Variable bitrate: 1.2 - 8.5 bits per sample
  • Constant and variable bitrate (CBR and VBR) modes.
  • Fixed frame length: Enables constant-time seeking.
  • Multi-channel support: Handles up to 255 channels.
  • Metadata storage: Allows embedding additional information.
