What mixdown options are offered by Auria in terms of Bit Depth and Sample Rate ?

The mixdown options are: 16, 24 and 32 bit WAV and AIFF files, and MP3 files. The mixdown uses the same sample rate as your project rate, which can be 44.1, 48k or 96k.

Starting in v1.06, there are also two new options: stem mixdown (will mix each track down, using any effects and automation on that track), and M4A format.

Thanks Rim,

It really is the real deal.

If you decided to implement Audiobus support, would the same audio quality options be available for recording internally into Auria from other iOS apps on the same iPad ?

Audiobus will be supported (probably in the next update). Auria will record whatever audiobus gives us when enabled, so if you're recording from a 24 bit app, it should record in 24 bits.

Just to make sure I'm not confused ;) and i often am. When you say Audiobus will be supported " probably in the next update", are you referring to 1.06? I didn't see it listed in the release thread detailing 1.06. Not trying to pressure, just curious. Thanks.

BTW PianoVerb is excellent!

I really have no idea when Audiobus will be ready. It's still being implemented, and we're working with the Audiobus team to make it happen. They've had to rewrite sections of the code in order to support DAWs like Auria. I'm hoping for 1.06, but I really can't say for sure.

Are there any 24bit apps out at the moment ?

Ha,

Nice one.....are there any known soft synths on iPad that are 24bit that would be good to bus into Auria once it updates with Audiobus support ?

Thank you Rim

I can't speak for anyone other than myself, but its worth the wait if the delays are to make sure it all works right. Though, I am very eager to get to work with it and Auria. The iDAW without peer.

I'm still not sure it matters at all. There's nothing wrong with a 16 bit synth going into a 24 bit DAW. I challenge you to need more than ~95 dB dynamic range when you're using a soft synth.

Thanks Dominic,

I am still new to the technical side of digital audio jargon vs reality.

This article helped me make a bit more sense of it...and it sits nicely with your comments.

Dave,

That article does a good job of explaining the playback process and is technically accurate, but doesn't help much with the recording side of things.

When you have the unpredictability of live sounds in audio recording, the wider dynamic range of 24 bit conversion allows you to make a bigger 'mistake' with level settings before you clip the input. In other words, because a sound hitting the digital 'brick wall' of 0dBfs is a horrible noise, you can record at a lower average level with 24 bit and still capture everything. (This all assumes that your mic pres and indeed your A/D conversion behave in a linear fashion and don't sound considerably worse at a lower recording level).
But generally, a soft synth will have absolutely no noise floor at all, and most of the time it's playing, the differences between quiet and loud (even within, say, a single piano note attack and decay) will be well within 16 bits of resolution.
Auria will simply dispose of the 8 bits of 'nothingness' at the bottom of the signal and all should be well.

In a similar way, a general tendency to aim for higher sampling rates (96 or 88.2 KHz) as opposed to 44.1 or 48KHz is usually missing the point. Better A/D and D/A converters tend to send good at whatever rate you use them at, and rubbish ones sound rubbish, whatever you set them at. But that's a different discussion.

Hi,

Thanks for your time and support.

Will be getting Auria once the Audiobus update goes live and hopefully putting this whole technical ordeal behind me to get groovy again....

Again thanks for your time Dominic.
