I wasn't sure which area to post this in, but hopefully someone can help me with this...

I'm looking into digitally ripping all of my CDs and storing the music in the computer so I can simply stream the audio to my home theater system via the blu ray player. I do not want compressed music, so I'm ripping lossless wave files into the computer.

I do not have any problems getting the music to playback through streaming, but I do have a problem with gaps that are created somewhere in the ripping process (or in the playback process?).

I have a lot of classical music, and there are many discs where the music does not stop when a new track/chapter starts...basically the music continues playing right through the track change. However, when I rip a disc onto the hard drive, there is a gap between tracks when I try to play it back on the computer or when streaming the album, which is very, very annoying and completely ruins the listening experience.

So, where is the problem with this? Are the computer and blu-ray player unable to stream back-to-back tracks seamlessly without a gap between them, or is it something in the ripping that is creating audio gap between tracks? I know when burning discs some software gives you an option of a gap or not, but that it not the problem here since we are just ripping and then streaming.

Any thoughts, solutions or help with this would be appreciated.

You can use an audio editor such as Audacity (Open Source Freeware) to merge the separated tracks back into single files.

If you have the right burning software, you can burn the individual track files without gaps, using a feature called "Disk At Once".

Thank you for the response.

However, as I said in my post, this is not about burning CDs.

The problem here is the actual files that just sit in the hard drive to be streamed. Would Audacity create a 'disk at once' file that would sit in the hard drive that would be able to be streamed via Wi-Fi without gaps. That's the problem I have.

As far as computer music playback software is concerned, a quick google search should throw up a good few examples of decent gapless supporting players, certainly for bog standard WAV files. The better players should definitely support gapless with other lossless formats too, such as the compressed FLAC & ALAC (Apple lossless) and Apple's uncompressed AIFF. I use the excellent free Foobar2000 music file player on my Windows computers, as it's highly configurable with a wealth of plug-in components and has a very decent support community. However, it can be a bit 'klunky' to those who are new to it.

Unfortunately, it's quite rare for a UPnP/DLNA streaming bluray player to support gapless playback. Even mainstream hifi stereo streamers have had the same problem and fortunately the majority now have gapless support, but only after firmware updates, eg's: Denon DNP-720AE, Marantz NA7004, Pioneer N-30 & N-50 & Cambridge Audio NP30 & Stream Magic 6, etc. Finding a solution to your bluray player's lack of gapless support will possibly depend on its UPnP/DLNA capabilities and will almost certainly not be very elegant.

You could merge all the album tracks into one file, as suggested by Arnold, as this should definitely work. However, losing the individual tracks will mean you'll no longer easily be able to locate individual movements within your classical music albums, for example. You'll also need to take into account the time taken to merge all the tracks of the required albums in your collection, not forgetting that unless you keep a copy of the original files, the process will be nigh on irreversable should you go on to acquire a gapless supporting streamer.

There's another possible solution that does not alter your cd file rips, but uses specialised computer sound capture software to create a UPnP/DLNA streamable music file, very similar to an internet radio file. Hence if your music player software is playing the tracks without any gaps, the captured sound will too. It's the UPnP/DLNA equivalent of Apple's Airplay. However, by nature these files are of unknown length, a feature which will need to be supported by your bluray player's streaming mechanism - but it's certainly worth trying. If your computer is a Windows machine, there's a couple of free applications you could give a go.

Firstly there's the free foo_UPnP plugin component available for Foobar2000 music player I mentioned, that gives Fb2k full UPnP/DLNA streaming capabilities, providing a UPnP/DLNA controller, server and renderer. However, what's relevant here is it also has the option of creating a UPnP/DLNA streamable file from the playlist of music tracks that's currently being played by Fb2k.
The other application to investigate is a UPnP/DLNA music server that captures the sound of the current application to create a UPnP/DLNA streamable file with, ie, it can be used for ANY music playing application. This is the free ('donation ware') Stream What You Hear UPnP/DLNA server.

Note that these streaming methods require the music data to be buffered, so there is a noticeable delay of usually 1-3 seconds when controlling the music playback. For example, the music will carrying on playing on the streamer for a few seconds after hitting pause on the computer's music player software.

Then forget the comment about the burning software. The comment about the audio editor still holds/

No, Audacity would create a single .wav file that sould sit on the hard drive and play without any added gaps/

Upon first glance I thought the title of this thread was "trouble with gas when ripping." eek.gif
