Yeah the North American model's remote only has buttons, no lcd. They always sell a step-down version remote in North Amerca because most Americans don't have a use for the expensive kanji features of the Japanese remotes. Is it true that the only color being release in North America is black? I tired to find out, and all the American eTailers only sell black models. Does anyone know if black is the only color?

I'd like to know once you've tried it out... Does the RH10 play MP3's gaplessly? If not, roughly how much silence is there between the end of one song and the beginning of the next?

I tested it out and attached an mp3 file of the results to this post(played the split track into line-in) there is a note that plays twice and has a gap in the middle each time. the first time it plays is the Hi-LP gap, the second time it plays is the mp3-160gap

[attachmentid=195]

Here is the important information:

Hi-LP gap: 160ms (.160 seconds)

mp3-160 gap: 122ms (.122 seconds)

I measured these gaps using GoldWave

(I only tested once so this wasn't an average of the gap or anything, but it seemed to be the same each time I played it)(Also this was done with the quickmode setting turned on, but it also didn't seem any different with it off)

Hope this helps to answer your question happy.gif

Huh, shouldn't Hi-LP be totally gapless? Or at most something around a couple of milliseconds?

kungfool, two questions:

1) what was your original signal, an audio CD or two wave files?

2) did you encode the files in one run, or seperate?

Original signal was one wav file, I made it using Propellorhead Reason, it's just a long note...

Then I split the wav file using GoldWave so that it spread across two wav files...

Then I encoded each wav file using CDex into mp3-160 (lame)

Then loaded them into Sonic Stage 3.0 (JP) and downloaded them to the RH10 leaving them as mp3, then downloaded a copy of the tracks (still encoded into mp3) letting Sonic Stage convert them into Hi-LP as it transferred.

Played back all four tracks (two notes x split in half) into line-in and recorded the results...

Then preceded to measure the size of the gap back in goldwave...

Then encoded the line-in results as mp3-32-mono (lame) for upload to the internet.

Oops, I didn't know CDex doesn't encode gapless... Can you recommend an encoder that would produce a gapless mp3 so I could do an accurate test?

Umm... There is no such thing as gapless MP3. MP3 will have gaps by it's very nature. Some DAPs however, are clever and circumvent the gaps by detecting null signals, etc.

But Lame adds information, which is necessary to remove the gap, in file headers.

On the other hand, there is no such thing as gapless atrac. Atrac(3/plus) just appears to be gapless because is has same block length as cd audio thus producing gapless results from cd sources.

Yes that's what I mean. Gapless MP3's don't exist, but gapless MP3 playback does. CDex doesn't include information that is necessary for this to happen. I wonder if SonicStage will read it anyway, but that's another story.
