Most appropriate sample rate

Most appropriate sample rate

Youngling Posts: 24 Join Date: 4/6/17 Recent Posts

Hello,

all of my my audio sources are digitally connected to two 8351. Because DSD isn't supported directly, I have to convert my collection of DSD files to PCM, which is supported by 8351 up to 24/192. A "natural" (?) sample rate for DSD to PCM conversion is 88.2 kHz, potentionally 176.2 kHz.

My question:
Which input sample rate would be "generic" for the 8351, i.e. a sample rate to be processed inside the 8351 without an internal sample rate conversion?

Regards
Herbert

Let me reply my own question.

Digging deeper into the forum, I found several places with the information that the 8351 always uses 24bit/96kHz for the tweeter
and 24bit/48kHz for the midrange and woofer. So I decide to convert my (big) DSD64 collection to 24Bit/96kHz PCM.

Hello,

before I start to convert my collection of DSD-files to 24Bit/96kHz PCM, I think it would be very helpful to know something about the samplerate conversion capabilitites and algorithms of the 8351. In particular about the quality of the resampled audio in the case of DSD converted to 96kHz PCM, where an interpolation by a factor of 147 then decimation by a factor of 160 comes into play.

Hello Herbert,

We recommend to use 96 kHz sampling rate if you plan to convert your files. It should be the most appropriate option for our monitors.
