{"name":"soundmodem","summary":"Audio based modem for ham radio supporting ax.25","description":"This software allows a standard PC soundcard to be used as a packet radio \"modem\". The whole processing is done on the main processor CPU.\nUnlike previous packet radio modem software, this new release offers several new benefits:\n  - Now uses standard operating system sound drivers (OSS/Free under Linux, /dev/audio under Solaris and DirectSound under Windows), thus runs on all soundcards for which drivers for the desired operating system are available.\n  - No fixed relationship between bitrate, sampling rate, and modem parameters. Modems may be parametrized, and multiple modems may even run on the same audio channel!\n  - Usermode solution allows the use of MMX, VIS, Floating point and other media instruction sets to speed up computation.\n  - Cross platform builds from a single source code provides ubiquitous availability.","homepage_url":"http://soundmodem.vk4msl.id.au/","license":"GPL-2.0-only","attribute_paths":["soundmodem"],"releases":[{"version":"0.20","last_updated":"2026-01-23T17:20:52Z","platforms":[{"arch":"arm64","os":"Linux","system":"aarch64-linux","attribute_path":"soundmodem","commit_hash":"a1bab9e494f5f4939442a57a58d0449a109593fe","date":"2026-01-23T17:20:52Z","outputs":[{"name":"out","path":"/nix/store/mclcwv8znf4qnpgcsf6ak63px99n4pkf-soundmodem-0.20","default":true}],"broken":false,"insecure":false},{"arch":"x86-64","os":"Linux","system":"x86_64-linux","attribute_path":"soundmodem","commit_hash":"a1bab9e494f5f4939442a57a58d0449a109593fe","date":"2026-01-23T17:20:52Z","outputs":[{"name":"out","path":"/nix/store/hbl7dvr4a9ra9i4ij4myh2wqr0vxa83d-soundmodem-0.20","default":true}],"broken":false,"insecure":false}],"platforms_summary":"Linux","outputs_summary":"","prerelease":false,"broken":false,"insecure":false},{"version":"","last_updated":"2022-03-21T18:25:50Z","platforms":[{"arch":"arm64","os":"Linux","system":"aarch64-linux","attribute_path":"soundmodem","commit_hash":"4c3c80df545ec5cb26b5480979c3e3f93518cbe5","date":"2022-03-21T18:25:50Z","outputs":[{"name":"out","path":"/nix/store/f2v4iwyhrqhf0v0687wi9bhvrc1318fs-soundmodem","default":true}],"broken":false,"insecure":false},{"arch":"x86-64","os":"Linux","system":"x86_64-linux","attribute_path":"soundmodem","commit_hash":"4c3c80df545ec5cb26b5480979c3e3f93518cbe5","date":"2022-03-21T18:25:50Z","outputs":[],"broken":false,"insecure":false}],"platforms_summary":"Linux","outputs_summary":"","prerelease":false,"broken":false,"insecure":false}]}
