I have three sources of audio feeding into my A/V receiver. One is for video games, audio goes straight to the receiver and video to the TV so they're pretty much in sync (except for the TV delay, of course). The other comes straight from my Blu-ray player to the receiver, so that's fine. But the problem is with my LaserDisc player. The scaler I'm using right now is an iScan HD. It has digital audio inputs and outputs for video/audio syncing, but nothing for analog audio. My receiver doesn't have input dependent delays, so if I delay for my LaserDisc player, then I delay my Blu-ray player and game consoles. So my question is, does anybody know of a device that will delay analog stereo audio? Ideally, it wouldn't process the audio at all, just hold it for a set amount of time then spit it back out in the same format it came in.
Thanks in advance for any help

I *think* I own a pair of RCA cables that has some sort of box in the middle with separate delay knobs for audio and video. I'll check when I get home.

Ok so these are the cables I was talking about: http://www.ebay.com/itm/RECOTON-V616-Vi ... 9977790608There are 2 knobs, 1 for audio and 1 for video but the description only reads: Min/Max. I don't know if this refers to a delay or if it simply "enhances" the signal in some way.

I don't know if this refers to a delay or if it simply "enhances" the signal in some way. I would be very cautious with this. I don't think this is delaying any signal. Looks kind of like voodoo to me. Perhaps a signal augmenter used for long runs? Nonetheless I don't see any indication that this could be used for audio/video syncing issues. Just my 2 cents, could be wrong.

I remember I used to have a Sony receiver and whenever I'd turn on the DSP, it'd sound just awful. Would it be like that? (the receiver was quite old, early 90s) What you select really shouldn't matter, even with the lower setting your talking CD quality and the original audio stream on Laserdisc is this quality. In terms of what you hear it's not the bitrate/sampling rate that's the issue but rather how good your DAC is in your system for encoding/decoding digital to analog and vice versa. If you buy a descent DAC then you shouldn't have any noticeable artifacting. Overall sound quality is ideally limited by the source not your encoding equipment (but this may require that you spend money on good equipment).
