Xmedia recode fraunhofer aac9/25/2023 ![]() ![]() But if the audio was already AAC, just copy it over. Examples such as FLAC or DTS-HD to AAC/AC3, or AC3 640 to AAC 160 etc. The only times I'd re-encode the audio would be format support or a significant reduction in file size. Even if you encoded it at 320 Kbps, all you'd achieve is lower sound quality, Media players are capable of down-mixing 5.1 AAC to stereo. If the original audio was AAC 5.1 212 Kbps, I would simply copy that over, I would not re-encode it to stereo. An increase of 73 MB or 0.07 GB, which is roughly the difference in size between your two files.Īs to how you encode the audio, it depends on the source. In your example, a 94 minute 212 Kbps AAC = 143 MB file size, encoded at 320 Kbps the file size would become 216 MB. If you look carefully at the Media Info details for each file, it will show you the actual file size of each element (video track, audio track(s), subtitles etc.) along with its actual bit rate. Original file prior to converting the audio:įormat/Info : Advanced Audio Codec Low Complexity with Spectral Band ReplicationįILE AFTER CONVERTING THE AUDIO (File is Now Larger than prior to converting the 5.1 audio)įormat/Info : Advanced Audio Codec Low Complexity Would I change the bitrate in XMedia lower than 320 in this case? The rate control mode is set to average bit rate (that's the only option) When I look at the original file in media info, I see Sampling rate : 48.0 kHz Bit rate : 212 kb/s. xmedia recode ist ein kostenloser video converter. ![]() Generally, the AAC / 320 kbps works great, however there are times when the resulting file turns out larger than the original file that has 5.1 audio.įor example my video went from being 1.26 gb to 1.34 gb. Topics: aac, ape, audio, decode, encode, mediacoder, mediacoder official website. ![]() I use this to convert my files (copy the video, only change the audio to accommodate my soundbar). The process takes on average 90 seconds per 1 GB of file size, it's very quick. ![]() Press the encode button at the top and XMedia will copy over the video track (untouched), convert the audio track (and copy over your DTS if set up), copy over any subtitles and create a new MKV file. Click the Tag tab and give the video a title, then click the Queue tab and click the large blue cross at the top to add your task to the list. If there are subtitles, go to the Subtitle tab and add those. You can also copy over the original DTS track, if you want, so you've got your basic stereo AAC track now, without losing the 5.1 DTS track, if you upgrade your setup in the future. Click the blue arrow to move your track to the right-hand window, and check its codec and quality settings match what you want. In the Audio tab, select your DTS track, ensure Mode is set to Convert, Codec is AAC, Channels is set to Stereo, and Bitrate is set to 320kbps. You often need to clear the track, then add it back in to ensure it's in copy mode. In the Video tab, change the Mode from Convert to Copy, check the output window shows your video track with Copy under the Modus heading. Try that to see if it does what you want.In XMedia Recode set your output format to Profile, Custom and Format, Matroska, file extension will be MKV. Or, since you analyzed in Audition, you probably have access to the Adobe Media Encoder. If you don't mind paying some money, the tmpgenc plugins I mentioned also offer more options, but no low pass control, so I don't know if they are allowing higher frequencies, and their full mastering works suite may give you more options again. Use the MOV file as a source and something that gives you some controls to achieve what you want, I would recommend XMedia Recode as a free test, as it does have the Fraunhofer FDK AAC codec available, which is supposed handle those high frequencies better if you set the low pass filter to something higher, (although that codec variation is also designed for phones). MP3 did cut frequencies above 16kHz, and while AAC does technically allow for higher frequencies with the right settings made, most AAC codec implementations still do the same kind of frequency cutting because, as I said above, most people don't hear very much above that 16kHz to 18kHz area.įor your purposes in wanting frequencies above 16kHz, I would suggest not using the built in edius mp4 exporter. It is a lossy compressed audio codec, so no matter if there were settings there or not, it will never be the same as an uncompressed PCM used in a MOV file.Īll that said, AAC was designed as a replacement for MP3. Ok so the built in edius preset uses AAC-LC audio. ![]()
