I know how to set levels, but this is objectively better. Audio is unpredictable. People make mistakes. This solves both problems. If you're a musician, just have this thing recording every time you sit down to practice or jam. You might capture some magic and the levels will be fine no matter what.

Exactly, it's a HUGE quality of life improvement. I also noticed that using this changes how I use a lot of my microphones. It's no longer about which mics capture the most information within that narrow decibel band during recording. It's about the tone quality that I get _after_ I adjust the levels and compress it. Some passive dynamic mics are able to give me much more detail and fuller sound than my condenser mics in post. Also, no longer needing _extra_ preamps on things like ribbon mics is a huge win in the battle against the noise floor. Biggest drawback, though... you gotta be really on top of your room treatment. You're also gonna become keenly aware of the inherent noise in your setup.

Nice review. Thank you for always include hp output in the review 👍🏼

that is pretty badass! as a guitarist, there are so many smaller interfaces that just cannot handle really high output pickups, even if you set the input gain to minimum. so you'd need to mess with DI boxes or find an interface with a pad switch. this seems like a really good interface overall, especially at the price. 5ms-ish RTL is acceptable to me.

On MacOS Core audio supports 32 bit float and even Apple's own ARM based laptops have a 32 float converter for the internal microphone for Macbooks. Even though MacOS supports 32bit float recording though out the OS but there are certain applications do not. Logic Pro and Mainstage does not yet support recording or inputing 32 bit floating point audio only 20 and 24 bits. But Reaper, and Pro Tools do support it already. As well as MacOS's screen capture software and Quciktime recording does support it. I think this years OS update will have full 32 bit compatibility across all Apple made Mac Apps that support audio recording. The Logic/Garageband/Mainstage team have said 32bit float recording will come before the end of the year to those app and it will probably come to final cut very soon after that! Cheers Julian always great work!!

wow fantastic review

Terrific video, Julian! So 32-bit float audio with two ADC's is somewhat analogous to High Dynamic Range technology in cameras, where two images are taken at two different sensitivities in order to capture detail in both bright clouds and dark shadows. The end goal with both technologies is to capture the dynamic range of the real world without clipping and then eventually compress the information into smaller range for playback: 1.6 billion nits for the sun compressed down to 2,000 nits of brightness on your iPhone screen; or 190 db of sound compressed down to a CD-quality stream for your earbuds.

As mentioned in the video oc it can still clip... people should not forget that 32 bit float is just a "storage format". Everything before that is still hardware and has a physical limit. Starting from the microphone that has a maximum peak pressure all the way down to the ADC that has a maximum voltage input

@artysanmobile

The design for FS= +24dBU at the input connector makes that, if not impossible, at least practically so. Power supply voltage is the limiting factor. Sources would need a 40+VDC power supply, almost unheard of today. The key is that any conceivable operating scenario will be physically unable to reach that voltage, hence no input gains.

Hey Julian, I would love to see you do a video on the Zoom F3. While I know it is similar to the UAC-232 and likely uses the same ADC schematic, it includes for example, a 24-bit MME driver mode for plug and play interface capability, which you asked them for in this video. Thanks as always!

FL Studio can record 32 bit float into Edison and into the Playlist. I believe this is ASIO or CoreAudio only as these are low latency drivers, MME (used to be 16bit until Windows 2000 or something ) and other internal cheap stock soundcard solutions will typically be 24/32bit either depending on the source and can be weird sometimes not allow the passing of data samples as processed from the bus (USB port) but instead as CAPTURED (via the driver). Make sure your drivers are 32bit float and updated, as well as your recording software. p.s. apple users, I think Logic is 16bit until you hit 24bit BWF recording etc, I have no idea if 32 bit is a thing or is planned. I rarely use Logic other than for mixing.

Great video as always!!, a year ago you made a video about how to plug your headphones to your interface so I followed the instructions and it works perfect but you never showed how to unplug.

I think the biggest thing for this interface is super hot active guitar pickups or active bass preamps. No internal clip and just setting the input properly in the app, I'll be good to go. The Focusrite 2I2 second gen can't handle hot pups without mild to moderate cliping. I generally don't care as I play metal, high gain ampsims, but it does effect cleans and edge of breakup tones. Excellent video.

Thank you for the review! I appreciate the part about 32 bit float compatibility with different capture programs such as OBS. Do you think you could try the obs-asio plugin with OBS to see if that fixes the issue?

For hi-z direct guitar this is important. Early entry level interfaces drastically lacked the dynamic headroom for things like active pickups. I've recently been using a Vox ValveEnergy "Nu-tube" pedal as a (clean-ish) preamp into digital amp sims. IMO it "feels" more authentic and makes using analog pedals direct noticeably more convincing.

nothing beats proper gain staging and understanding the basics.

Good grief, I'm still using Cool Edit Pro 2.1 from around the early 2000's, and I do everything in it using 32bit floating point format. Of course, CEP was way ahead of its time, and IMHO much better than what Adobe replaced it with (Adobe Audition), but it wasn't really set up to support the more modern workflows that have evolved since, especially when they rely on GPU's. And no other ADC has yet output 32bit floating point for recording, but I would record from any normal 24bit ADC as 32bit float in CEP (and of course, you have to set the levels to avoid clipping, but with 24bits that isn't hard to do). But I'm astonished to hear that people are still using software that cannot record in 32bit floating point format! I mean, really, I've was doing it 20 years ago with CEP!

Julian, I would like to see a review of Roland interfaces.The old Quad and Octa capture interfaces were highly regarded because they had a very good mix of hardware and software. I would like to know if it's still the case.

Single handedly saved the music hardware part of the feed from another MPC X LE video lol Question/Concern: "Everyone's" argument usually goes something like "32 bit is unnecessary, cant reasonably capture or perceive that range, the file size!" & some other Hot takes... Answer: "Cool, don't use it then... 😆" Seems to be good for non-Audio Engineers, especially those with a noisy home studio or those who record out and about with mobile setups (outdoors or even all types on non treated rooms ie hotels & so on) Of course the mic/outboard preamp situation is a big factor but simply capturing everything after that fact enables ONE to do the rest in the box without jumping through a labyrinth of hoops Another interesting product is the Rode NT1-A 5th Gen USB/XLR mic. The catch is that the 32-bit float recording is built into the mic and is only possible when using the USB port. XLR is only 24 bit. Regardless would be interesting to see a side by side with that mic on USB (32-bit float) and then running through the 232 via XLR at 24 bit 🤔

I purchased Rode NT1 5th generation which has 32bit recording capabilities.

Lightning strikes in the studio, not just during field recording.

It works well, I tested it in Reaper and sure the dynamic range is there. Maybe you are right, maybe this is the future. I remember many complained about Reaper not having separate midi, audio, group, and aux tracks, but only one type of track to be used for everything you need.

Though adc should be integer, that's a lot of wasted space

The more I learn from you about 32 bit float and merging two DACs, the more skeptical I become, wether this would be of any use to be. My current setup consists of a MOTU M4 Interface and a Shure Beta 58A dynamic microphone. I have set it up for about 25dB of headroom over normal talking. And my SNR at 64dB even after 21dB additional gain via a maximizer plugion vs Selfnoise is already extremely low as is. So... I don't know... Dual DAC and 32bit float seems to be quite gimmicky, at least for most uses. Stil.... adding that much dynamic range is quite a nice job.

@@GuyGamer1 I’m from back in the day when they used double system location recording in movie making, recording on a nagra (reel to reel) with some sort of mixer between the mics and the nagra. The crew position was called “mixer”. The mixer was responsible for getting the best audio recording possible, which as you can imagine was/is pretty important. Good mixers were paid well. Bad audio can be fixed in post, but back then post production processing was expensive. Mixers (and their boom operator assistants) were not to be trifled with, as they could listen in to private conversations. But they were also in the know with all sorts of useful insider information, such as when’s lunch? I don’t think we regular crew people gave them enough credit or patience. We’d grumble about delays while the mixer chased down ambient noise, like a refrigerator in the next room. We’d groan when they had to track down the source of line noise. “Hold for sound” is not what you want to hear when you’re one or two takes away from lunch. Anyway, these days the demand for people that “know what they’re doing” far exceeds the number of people with those skills, no matter the level of production. While 32-bit float is going to be perceived as a magic bullet for many “content creators” (especially solo creators and small teams), the need for skilled technicians such as yourself is not going away. The float is just another tool.
