  C: Digital Voice mode for HF Radio
Description:
  fr: >-
    <p>FreeDV est un mode vocal numérique destiné à la transmission et la réception radio de haute fréquence (HF). Il utilise un modem
    de multiplexage par répartition de fréquence (FDM) avec 15 porteuses et aucune correction d&apos;erreur directe (FEC). Un encodeur/décodeur
    vocal bas débit (Codec 2) fournit une qualité vocale sans fatigue auditive causée par le bruit et les interférences habituellement
    associés avec les voix analogiques à bande latérale unique (SSB). Un transmetteur HF SSB, un ordinateur et deux cartes son sont nécessaires.
    Les simulations de propagation et les tests HF à l&apos;antenne ont montré que le décodage de la voix est possible pour un rapport
    de signal sur bruit de 4 dB.  Le logiciel FreeDV a été développé par David Rowe (Codec 2, implémentation du modem FDM, intégration)
    et David Witten (interface graphique, conception de l&apos;architecture). La conception de FreeDV et l&apos;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>

    <p>FreeDV er en digital lydtilstand for transmission og modtagelse af højfrekvent (HF) radio. Programmet bruger et frequency division
    multiplex-modem (FDM) med 15 carriere og ingen forward error correction (FEC). En stemme koder-afkoder med lav bithastighed (Codec
    2) tilbyder en lydkvalitet uden lydtabet medført af støj og interferens som normalt følger med analog single sideband-lyd (SSB). En
    HF SSB-transceiver, personlig computer og to lydkort er krævet. Stisimulering og on-the-air HF-test har vist at afkodning af lyd er
    muligt på et signal-til-støj forhold på 4 dB.  FreeDV-programmet blev udviklet af David Rowe (Codec 2, FDM-modemimplementering, integration)
    og David Witten (grafisk brugerflade, arkitekturdesign). FreeDV-designet og brugergrænsefladen blev baseret på det tidligere FDMDV-program,
    som blev udviklet af Francesco Lanza. FDM-modemdesignet og udviklingen blev understøttet af Peter Martinez.</p>

    FDM (multiplazione a divisione di frequenza) con 15 portanti e nessuna correzione degli errori FEC (Forward Error Correction). Un
    codificatore-decodificatore (Codec 2) vocale a basso bit-rate fornisce una qualità vocale che non affatica l&apos;ascoltatore con
    rumori o interferenze normalmente associati con la voce analogica SSB (Single SideBand). Sono necessari un ricevitore-trasmettitore
    SSB HF, un personal computer e due schede audio. La simulazione del percorso e test HF in onda hanno mostrato che la decodifica della
    voce è possibile con un rapporto segnale/rumore di 4dB.  Il software FreeDV è stato sviluppato da David Rowe (Codec 2, implementazione

    <p>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)
