You can get in from the first post in this thread.

How about trying the download link in the first post?

Well, in principle ...

I've downloaded and tried that one first.
It didn't work as it should work (looped the first samples of each track).
So I was looking for a fixed version in the growing thread.

BTW: @Dotpitch: Thanks for the friendly hint.

Well duh, didn't see that there was already a new page. :)

Looking at the dates, that is the latest version.

Could you explain that a bit more? Does it keep looping the first second indefinitely, or doesn't it clear its buffers properly? Does it happen with all tracks, or just with some? With what encoder were those files made, and do they contain album art?

Hi, I have a question regarding this plugin. Does it support AAC HE and AAC HEv2 (SBR + Parametric Stereo)?

If so could it be possible to notify this in the info window? Right now it only says Advanced Audio Coding (MP4)... which is nothing really because you can tell that by the extension of the file.

Yes, it does.

Actually, that is not something you can see from the extension, since MP4 can contain different audio formats as well. I'll put it on the suggestions list.

Thank you very much. I'm listening so some Internet radios which use AAC at about 40-50Kbps (so AAC HE is presumed) and would like to do it with XMPlay.

Thank you for the explanation, I've read more about it and you're right; MP4 is a container which can have several things inside (and M4A is only a extension rename).

Adding the info about which AAC version it is in the info window would be interesting, like VBR and so for mp3 files.

Thank you very much Ian, it shows now the type of AAC. I've tried several streams and identified all of the kinds. The only thing is that HEv2 uses SBR too, to be accurate it would be (SBR + PS) and the (LC) notation for the simple AAC may be droped as all of them use LC (they are kind of encapsulated from what I've seen today: http://en.wikipedia.org/wiki/High-Efficiency_Advanced_Audio_Coding). but as it is right now you can tell which kind of AAC you have there anyway.

By the way, I'm Chark, glad to be here :).

Hello Ian,

Speaking on the AAC & MP4 topic, I sent to you an m4a file, which I've had problems playing (it skips) for some time. Do you you know why is this happening? It plays fine on other audio players. Please let me know if you received the file correctly.

Thank you in advance!

With DirectSound, if I play, stop, and then play a file again, I hear a bit of unflushed buffer before the new playback begins.

Does that happen with all files, or specifically with AAC files?

The file was received, but it is actually an ALAC file. I couldn't hear any skipping from it, so perhaps you are currently using an older version of the ALAC plugin? Let me know if it still skips with the latest version, and if it does, is there a particular point where it skips or is it throughout?

It skipped throughout. I was not aware that I needed the ALAC plugin, that was the reason why it wouldn't play at all. I updated it in the custom exe and now I can play it flawlessly with ALAC rev. 3. Again thank you very much for the help! 8)

The buffer problem only occurs with AAC files.  It also happens without DirectSound.  Tested on two separate audio devices.

And is that only with DirectSound, or with WaveOut as well? I take it you don't unload the file when you stop playback?

Same result with WAV Writer.  Unloading the file (stop twice) gives a fresh start.

Yep, I can reproduce that with MP4 AAC files (plain AAC seems fine?). I'll look into it.
