FreeDV in Breadstick
Breadstick runs Debian's own freedv package for ARM64, the build a Debian 13 computer with an ARM processor installs, so FreeDV should look and behave as it does on a Linux PC. On Samsung DeX, Floating mode opens it as its own window beside your Android apps, and Desktop mode runs it on a full Linux desktop.
Sound plays through the device's own audio output, and video is decoded in software, so large or high frame rate files can struggle on slower devices. More about audio and video apps in Breadstick.
About FreeDV
From Debian's package description
FreeDV is a digital voice mode intended for transmission and reception over high-frequency (HF) radio. It uses a frequency division multiplex (FDM) modem with 15 carriers and no forward error correction (FEC). A low bit-rate voice coder-decoder (Codec 2) provides voice quality without the listener fatigue caused by noise and interference normally associated with analog single sideband (SSB) voice. A HF SSB transceiver, personal computer and two sound cards are required. Path simulation and on-the-air HF testing have shown that decoding voice is possible at a signal-to-noise ratio of 4 dB.
The FreeDV software was developed by David Rowe (Codec 2, FDM modem implementation, integration) and David Witten (GUI, architecture design). The FreeDV design and user interface was based on the earlier FDMDV program which was developed by Francesco Lanza. The FDM modem design and development was supported from Peter Martinez.
