HQPlayer e DRC...esperienze

[giordy60]

come ho scritto sopra, con rew puoi utilizzare 44,1 o 48 khz

[cicquetto]

ho fatto le acquisizioni ed estratto gli impulsi in wav. c'è qualcuno che puo generarmi i 2 filtri da inserire in hqplayer?

con drc interface non sono riuscito.

[Maggio]

Se guardi il video di Brigno è impossibile non riuscirci.
Lo trovi qui:

Il problema non è la generazione dei filtri ma riuscire a registrare uno sweep corretto!
Ciao

[cicquetto]

io parto dallo sweep registrato in REW che è pienamente compatibile con il mio microfono miniDSP.

in DRC interface ho problemi con il file del microfono, il mio file di calibrazione ha una struttura diversa da quello di brigno.

partendo dagli impulsi esportati da REW (a proposito, devo normalizzarli?) e salvati in adobe audition ho un errore quando li faccio processare da DRC interface relativo al file del microfono.

se ometto proprio il file di calibrazione del microfono il processo va avanti per poi interrompersi a un altro errore.

[Maggio]

Il file di calibrazione devi modificarlo.
Lo duplichi e cancelli le prime righe di testo, aggiungi il valore 00.00 00.0 all'inizio e 22050.00 0.00 alla fine.
Controlla che i separatori siano punti e non virgole.
Il file deve avere una struttura come riportato sotto.

00.00 0.00
10.054 -7.2819
10.179 -7.0988
10.306 -6.9187
.......
.......
19770.697 0.8748
20016.816 0.8400
22050.00 0.00

[Maggio]

I due files salvati da REW puoi importarli direttamente in DRC senza passare da Adobe Audition.
Una volta creati i filtri devi risalvarli con Adobe Audition.
Ciao

[cicquetto]

grazie, risolto con il file microfono

drc interface mi da lo stesso un messaggio di errore alla fine mi genera lo stesso i file, ecco il log per il canale sinistro

a questo punto devo convertire il pcm in wav per darlo in pasto ad hqplayer?

audition mi da vari formati wav, quale scelgo? e con quali opzioni?

[Maggio]

Se hai un errore non va bene... anche se ti crea i due files.
Sei sicuro della bontà degli sweep?
Domani, dal pc, ti indico come vanno salvati i due files con audition.
Se vuoi mandami i due sweep di partenza che controllo se mi dà errore.
