Signature: I am DTS, I carry 3 streams, HD-MA, HD-HRA and Surround (Core). The master chip should be flexible, but as long as it understands the data and mapping, all should be well. It would also be possible to use 2 or more channels to create larger single channels, for example, 4 as 2 96khz, 48bit. Lets say the first 2 channels are used as the audio ID, then 3-X for meta data, and so on. I can also confirm the DTS multichannel enhancer works on all channels for Interactive (192khz, 24-32bit, max).įound this, thought it was interesting: Photophone - WikipediaĬan be done with a channel based setup, 108 24bit, 48khz, 1152kbps per channel, where channels can instead be data pipes. My suggestion, for any unsupported formats, for any reason, uncompress it to PCM where possible.
Is ddp audio same as ac3 plus#
I also found that Dolby Digital Plus (DDP, DD+, E-AC3), will get downgraded to Dolby Digital Live (DDL, AC3), in SD (48khz, 16 bit). If I enable APO4 fully, and use DDL instead of Interactive, it improves quite a bit, quite funny, but its because its PCM, and APO4 will act on any PCM (analogue). Regardless, it appears to mostly unlock Toslink (SPDIF), although further tweaks might be ajf64, you are correct, the same audio transcoded to DDL and DTS Surround (aka Interactive), without APO4, DDL doesn't sound as positional, for SD the inbuilt enhancer does well for quality. I have attached something you guys can play with, unfortunately Windows doesn't have defaults for the test files. This works with encoders, such as DTS Interactive, too. My config and guide is here, and below is a screenshot of my current config for upmixing:
I use my own configuration, simply to setup stereo surround (2 channels to 5.1-7.1).
