DSD in LMS con SOX

**marcoc1712** · 22-02-2017, 15:57

MI servirebbe verificare una condizione specifica:

a. verificato che il DAC sia in grado di riprodurre DSD almeno 128x
b. verificato che squeezelite sia impostato per riprodurre DSD (nativo o dop non conta) almeno DSD128.
c. impostato il loggin di sistema (In Settings->Advanced):

- plugin.c-3PO = INFO.

d. impostato C-3PO come segue:

- GENERALI:

-- DSF abilitato
-- DFF Abilitato

- PLAYER

-- DSD64 abilitato
-- DSD128 abilitato
-- altri DSD abilitati o disabilitati, è indifferente.

-- DSF disbilitato x 'seek'
-- DSF disabilitato x StdIn
-- DSF abilitato per transcoding
-- DSF abilitato per resampling

-- DFF come DSF.

-- FLAC come DSF.

-- WAV come DSF + abilitato per seek.

- PLAYER (o generali SE quelle per player sono bloccate):

-- Resample Always
-- Target Sample Rate: Max synchronous
-- output format: dsf

il resto lasciatelo al default o come vi pare, ma evitate, per favore, extra effects.

Vorrei verificare che nel log (o nel terminale) si presenti una situazione come questa:

dove, ovviamente il mac address è il vostro.

Mandando quindi in play un brano in formato DSD64, nel file di log di C-3PO (v. ultima riga dei settings generali per la posizione) dovrebbe comparire qualcosa del genere:

Mi interessa sapere il valore di forced Samplerate che a me risulta 176KHz, viste le caratteristiche della mia scheda, ma vorrei capire coa ritorna in una scheda DSD capable di DSD128 o superiori (temo 768KHz al massimo).

Ripetendo la prova con un file wav 44100/16 in ingresso, si dovrebbe ottenere qualcosa di analogo:

Il che significa che NON è solo Squeezelite ad essere coinvolta, anche LMS ci mette del suo, in base al formato di input, complicando le cose.

Ripetendo la prova con un file FLAC, C-3PO (eseguibile) non è coinvolto, quindi non produce log, ma eventualmente si può verificare nel log del server, a me non funziona, come già descritto, ma vorrei sapere se con una scheda capace di DSD128 funziona.

Sarebbe interessante vedere il log del server, impostando player.source = INFO nel logging.

Grazie per la collaborazione.
