Summary:
C: Digital Voice mode for HF Radio
Description:
C: >-
<p>FreeDV is a digital voice mode intended for transmission and reception over high-frequency (HF) radio. It uses about
half the bandwidth of traditional analog single-sideband (SSB) voice. 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.</p>
<p>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.</p>

<p>Le logiciel FreeDV a été développé par David Rowe (Codec 2, implémentation du modem FDM, intégration) et David Witten
(interface graphique, conception de l'architecture). La conception de FreeDV et l'interface utilisateur sont
basées sur la version antérieure du programme FDMDV développé par Francesco Lanza. La conception et le développement du
modem FDM ont été pris en charge par Peter Martinez.</p>
