France has long used a single 440Hz tone as its dial tone, part of the national telephone signalling standards that differ from country to country. While many countries use dual frequencies or cadenced rings, the French tone is continuous and instantly recognisable to anyone who has used a landline there. As landlines faded and mobile calls replaced waiting for a tone, recordings of the sound moved online as a reference and editing asset. It is now kept alive by filmmakers, sound designers and meme creators who need an accurate European phone cue.
