waveform avec java

bonjour,
comment créer le waveform d'un signal audio avec java
c'es une pb que je soufre d'elle depuis deux semaine
merci pour vos aides

Qu'est ce qui te poses, problème?
l'enregistrement, l'affichage?

bonjour,
mon pb exactement c'es comment tracer la forme d'onde d'un son choisi
c'es à dire lire un son w au meme temps tracer sa forme d'onde
merci pour vos aides

Je répète ma question soit plus précis sur ce qui te pose poblème sinon il va être dur de t'aider.

Le son est il acquis sur la carte son ou lu depuis un fichier?
Dans le cas d'un ficher, quel format?
Est-ce l'aquisition/lecture des donnéeés qui te pose problème?
Est-ce le dessin de la waveform?

bonjour,
le son depuis un fichier
extension .wav
le problem c'es de dessiner sa waveform
je peux vous donné mon code

Code:

bonjour,
à ce point mon travail est trés compliqué ou quoi?
aucune réponse?????????,
:?

C'est tout simplement car tu ne donne pas l'impression d'essayer quoi que ce soit et que tu attends qu'on fasse le travail à ta place. Ce qui n'arrivera pas. D'autant plus que la recherche google n'a pas l'air d'être ton fort non plus.
