Mixdown and convertion to mp3 making sound speed up + iTunes problem

suddenly, when export mixdown mp3 in auditon 3, track has speeded , sounds 'chipmunky'. have tried @ mp3 conversion status , seems cbr , mp3 selected. 'appears' sound tells me different.   also, don't know if can everytime try import audio cd, .cda tracks itunes means can't import them. have uninstalled itunes (don't know possesed me install anyway!) , have gone through see if itunes related remains on computer can't see why still making cda files itunes versions?   hope makes sense   nick you need change file association on computer .cda file associate whatever program wish use play cds on computer.  in xp can go control panel>folder options>file types , change association there.   your mp3 issue sounds sample rate change issue.  can happen if sound card has variable sample rate playback changes depending upon program using it.  experiment, turn off windows sounds , see if mp3s play sounding correct. you never said if mp3 issue on computer....

hola gente, tengo un motor paso paso nidec 45m843b09 con su respectivo driver, nidec e164387 pewsz que posee 6 entradas: cw/ccw start/stop clock lock drive gnd 24v mi pregunta es que deberia ingresar en cada uno de esos y que tipo de entrada es (analogica o digital). supongo que en 24v ingresan 24v+, en gnd su respectivo negativo, cw/ccw seria la direccion (se ingresa 0 para cw o 1 para ccw creo), start/stop (0 para start o 1 para start?), clock (supongo seria el paso, que longuitud de onda tengo que enviar, y cada cuantos microsegundos de delay hay que enviarla), lock drive (para bloquearlo en una posicion?). desde ya gracias Arduino Forum > International > EspaƱol > Hardware (Moderators: surbyte, Hector_A) > Controlar Motor paso a paso Nidec con su respectivo driver en Arduino arduino
