First test with the new AAC encoder and it crashes... sad.gif Does anybody have the same behaviour ?

Seems like CT applied aacPlus technique to high bitrate aac encoding, now not only for low bitrate situation.

Listening test is welcome here.

Edit: BTW, does somebody know any frontend that can use all aac encoding options?

Quick test with one track of my CD encoded @ 128k. The result showed that they are totally different encoder (not bit-identical).

With "Coding Technologies aacPlus High Bitrate encoder", the encoded aac file was reported as samplerate of 88200 with foobar v0.8.3. Compared with CT's aacPlus encoder, it's bit-allocation fluctuate much more than the old CT's aacPlus encoder.

I think this new encoder worth a listening test. biggrin.gif


Edit: foobar2000 v0.8.3 cannot identify the m4a contained aac stream correctly (identified as LC-AAC). The raw aac stream be identifyed as double the samplerate.

Is gapless playback tweakable please?
I've re-ripped a live album and a studio one having EAC leave out gaps but there's still half a second of silence between tracks.
Is it a buffering issue maybe?

Gapless MP3 playback: How does it work? Is it using the encoder-delay like foobar2000 or the modified in_mp123.dll? Or is it just some kind of a smart crossfader?

DARcode: Try resetting the DirectSound output settings to default. The "buffer ahead on track changes" needs to be about 400-500ms to overcome the time it takes to start playing the next file. It was changed to 500 by default, but old Winamp installations might still be set to 0

amano: Dolby LC-AAC isn't being shipped anymore. However, the encoder from 5.12 might still be present if you installed over an old version.

Enig123: CT calls the new mode "Oversampled SBR". Basically, SBR is used to fill in frequencies from 16k-22k, rather than 8k-16k. It is oversampled to 88200 (harmlessly) in some cases. However, the CT decoder will play back at 44100 for MP4 files (where it can pre-configure itself using the audio descriptor)

kurtnoise: are you trying the encoder within Winamp? (i.e. ripping a CD) Or using a third-party front-end?

elmar3rd: it uses the delay information placed inside the XING/INFO header by LAME.

This version's default is 0, set it to 400 and it's working pefectly, thanks a lot!

Full_devices _is_ slightly larger.. 100k, approx. Enough to be able to upload to mp3 players, maybe? I don't know, try them all...

Yep. Sorry, that must have been a "leftover".

So there are 3 CT modes for us:
a) LC Mode
b) SBR-HE Mode for low Bitrates
c) special oversampling SBR mode

What do the bitstream options (MPEG 2 vs MPEG 4) do?
What do the accurate vs compatible options do with the MP4 container?

MPEG-4 bitstream enables the use of TNS (temporal noise shaping) and LTP (long term prediction, although I have no idea if the encoder actually uses it - i've heard mixed things about it). MPEG-4 should always be better, but older AAC decoder might not decode it.

The accurate vs compatible options are to help out old decoders. Older decoders might choke when they see certain SBR modes in the audio configuration.

We should thank Winamp for simply giving us access to an open beta download folder; no repeat of that fiasco having an early 5.10 build available and being hotly debated here after Winamp "recalled" it!
First (very small!) bug: aacPlus encoding 1998-2005 Coding Technologies.
Turn over the calendar page!
I've not yet seen any files with property described as 88.2 sample rate, perhaps because I encoded that aacPlus High Bitrate Encoder v1.2 at 160 kbps instead of the 192 it had initially defaulted at.
I would especially like to know how the resampled LC-AAC files work in iPods -- I have an iAudio X5.
But, I do have a Loox 720 PocketPC (2003 OS), and I'm now listening with TCPMP to files I encoded at 48 kbps with the parametric stereo option -- totally freaking awesome! I used Stanley Hwang's Media Coder, merely copying the newer 500 kb (vs 560 kb) enc_aacplus.dll to MediaCoder\codecs . The tags were correctly transferred from FLAC and are read in TCPMP. Transcoding speed from FLAC was slightly above 25x, comparing to about 29x using Lancer oggenc2 (and definitely lots faster than Nero's initial ver 7.0 implementation of tweaked low bitrate HE-AAC).
I think (sort of a question) that the space overhead for an MP4 container is more significant at these rates, and am glad MediaCoder created *.aac files smaller than what I got using MP4/aacPlus Encoder v1.2 with "File Information: Accurate Information" directly using Winamp 5.2.
One really has to wonder why there's no news of a Flash music player with playback support for these tweaked HE-AAC formats. Do the math -- an 8 Gb Flash music player filled with 48 kbps files is the equal of an iPod stocked with 26.6 Gb of iTunes store files (for $7,000 -- yeah, right!).

benski, I've been playing with another Transcoder GUI that gives the option of choosing MPEG-4 for the aacPlus Encoder v 1.2, and my FLACs were turned into *.aac, all about 2,500 bytes larger than what I had got with MediaCoder. Is that 2,500 byte difference devoted to Temporal Noise Shaping?
I notice that the *.m4a files obtained by directly ripping the original CD and encoding in Winamp with that same codec were around 35.000 bytes larger still. Is that difference simply the container and tag info or is there additional sonic goodness?

Not sure how MediaCoder is working, but the extra 2500 bytes are likely the result of 0 padding added when Winamp tells the encoder that input has finished.

The extra 35,000 bytes in your m4a file is probably tags and MP4 container overhead.

This is completely wrong.

TNS was already included in MPEG 2 AAC. The only relevant feature added in MPEG 4 AAC is PNS, which will help at lower bitrates. LTP isn't used by any sane encoder, because almost no decoders support it (FAAD2 does, but anything in hardware almost certainly wont). In fact, it's not even compatible with HE-AAC!

So, enabling this is safe except for very old hardware decoders.

FAAD2 has handled this for ages. (It's sometimes referred to as Downsampled SBR)

I believe this mode is a loss in almost all conditions btw, i.e. you will never get better quality than in normal modes. We have it in Nero AAC too, but it's disabled. Guess why tongue.gif
