Still experimenting with my new toy (Replay 3060). I notice a definite decline in sound quality at Standard speed vs. live, but haven't really heard a difference at Medium. Does anyone have the technical details on the audio compression and bitrates at the different recording speeds? How much of the stored program is audio vs. video streams? My default record setting is Medium; I'm wondering whether High quality would be better for music programs.


Specifically, I wonder about watching live through the box. I understand that when using the Replay's tuner all content is being buffered and presented at High quality, and if I look close I can see some digital artifacts in this picture vs. the live analog cable (not too objectionable though). I am more concerned about the audio -- is the audio degraded (ie. compressed then decompressed using a lossy scheme) from live when using the Replay tuner?

What your experiencing is normal for that model. I don't know what the spec's are, but the audio is better at high, worse at standard...that changed with newer units; they now record at the same audio quality (high) on all (standard, medium, high) settings.


And you WILL notice a difference between live TV and TV buffered "live" through the Replay. After all, it is compressed; like the audio.

I wouldn't ever record in the std setting on the 3ks because of both the audio and video quality.


chain777 is right, the best audio on a 3k was 32k sample rate at high only worse as you dropped down. Seemed silly since in a 4GB file audio even at 48KHz sample rate encoded at 224kbs is only like 150MB. I don't care if the 120MB vs 150MB space for better audio, I don't want to listen to something that makes my speaker sound like tin cans.


The newer 4 & 5k lines record always at 48KHz, the enconding bitrate chages, but the sample rate is always the same.
