Analog RCA IN to Digital SPDIF OUT
#1
Hi guys,

what do you think about this device "Analog RCA R/L to Digital SPDiF Toslink"?
So that I can do "Pit Perfect" like bronans thread [/url][url=https://forum.fanres.com/thread-2742.html]Laserdisc PCM Capture Guide.

It's recomment to use that for digitalizing audio from VHS?

I believe this would convert an analogue signal to digital.
Therefore with a laserdisc / DVD / CD, the player would already have converted the digital signal to analogue via it's internal DAC to RCA output (then this device would convert it back).
For bit perfect you need to bypass any conversion from the Digital Code on the Disc, in this case Toslink / Coaxial out to Toslink / Coaxial in.
This passes the Digital information (0 & 1s) for an external device to decode (or capture in this case).

I gather your laserdisc player has no Toslink or Coaxial out?

VHS doesn't have digital audio afaik, at least not a normal VHS. This could digitize the audio possibly, but let me tell you right away that digitizing audio in good quality will cost you more than 30 bucks. Smile There are vast differences in ADCs (Analog to digital converters) in terms of quality, with the best getting into the range of thousands just to digitize 2 channels. However personally I'd opt for a beginner audio interface in the price range of 200 to 300 bucks or so that has good values. You can look up RMAA tests of audio interfaces online, they show you things like the noise floor, distortion, frequency response etc.

I know that the VHS doesn't have such digital audio but I want to know how is the quality when I digitalize to digital from analog.

Daher hätte der Player mit einer Laserdisc / DVD / CD das digitale Signal bereits über seinen internen DAC-In-RCA-Ausgang in analog konvertiert (dann würde dieses Gerät es zurückkonvertieren). 

Für Bit perfekt müssen Sie jede Konvertierung vom Digitalen Code auf der Disc umgehen, in diesem Fall Toslink / Koaxial out zu Toslink / Coaxial in. 

Dies übergibt die digitalen Informationen (0 & 1s) für ein externes Gerät zu dekodieren (oder erfassen in diesem Fall). 

Ich stelle fest, dass Ihr Laserdisc-Player keinen Toslink oder Koaxial-Out 

hat? 

Mein LD-Player Pioneer CLD-D925 hat AC-3 RF, (Koaxial) und SPDiF, aber ich spreche von Digizalize von VHS, nicht Laserdisc.

Well, that's what I tried to answer. You get what you pay for, basically.

It must be the 'Bit perfect' and link to a Laserdisc capture thread that confused me.
To be honest now it's how I answered in English, and in German Wink
