    this forum is pretty knowledgeable but for the few people who wanna know a bit (no pun intended) more about 32bit float -

    Why 32-bit Float is So Good
    32-bit float recordings seem magical because clipped recordings over 0 dBFS can be fully recovered with zero distortion. See the below GIF for a demonstration of this “magic.”

    Clipped 24-bit vs. 32-bit float recordings after lowering gain in post. Notice how the 24-bit file remains clipped but the 32-bit float file perfectly recovers the data above 0 dBFS.
    Clipped 24-bit vs. 32-bit float recordings after lowering gain in post. Notice how the 24-bit file remains clipped but the 32-bit float file perfectly recovers the data above 0 dBFS.

    Before with 16 and 24-bit audio, this was not possible. If your audio peaked above 0 dBFS, the captured audio was permanently distorted because these formats lack the ability to record any data over this threshold.

    32-bit float can record audio data +770 dB above 0 dBFS and -758 dB below. This gives 32-bit float recordings an incomprehensible dynamic range of 1528 dB. This figure is hard to fully grasp because dynamic range between the quietest sound on Earth (an anechoic chamber) and the loudest sound possible (194 dB) is only 185 dB.

    With over 1000 dB of headroom above the quietest and loudest sounds on Earth, clipping is impossible. Distorted audio above 0 dBFS can easily be recovered in post by attenuating the signal.

    Here’s a great article from Sound Devices explaining this in greater detail: https://www.sounddevices.com/32-bit-float-files-explained/

    PRO:

    1528 dB of dynamic range

    clipped audio can be recovered in post

    can spend more time being creative and less time worrying about levels

    CON:

    takes up more storage space

    not all DAWs can read it (yet)

    A very knowledgeable and interesting post, thank you for this, had no idea it was possible to salvage clipped audio, that's pretty amazing

    yep, its really like magic to me.

    I discovered the magic of working in 32bit with the equally magical Syntrilium CoolEdit 2000, I think back in 1998. Saved me a lot of sessions 😊

    Confirming that Cubasis on iOS actually supports 32 bit float. I use my Zoom F3 to record my classes at 32 bit float and then use Cubasis on iPad to normalise. The clipped portion of the audio is easily recovered and then use Hokusai to edit the audio after normalising it.

    I sound like a broken record, but this thing is not 32 bit with iOS. It's 24bit. Even that is terrific for avoiding clipping, but isn't the same as 32 bit.

    [edit] Oh, I misunderstood. Sure, if you record standalone with the F3, then import to Cubasis, that's 32 bit all the way. People keep thinking that they can record direct into iOS at 32bit with the pictured unit, but if you read the fine print, it's only 24 bit on iOS.

    I'll shut up now.

    But not with that interface. It's in the fine print of the specs that it only works at 24 bit on iOS. Sure, Cubasis will upsample it, but the audio will come in at 24 bit, not 32 bit.

    Anyone here using this interface with iOS? (and/or Mac (Reason, Logic) ). I have a Focusrite Scarlett 2i2 and the cheap M-Audio Solo now and are not very happy with either.

    btw, Audio Evolution mobile has been upgraded to handle 32-bit float input, so that one can be added to the DAWs that will work at full resolution with this device.

  • dwraedwrae

    The latest version of Audio Evolution Mobile Studio supports the 32-bit floating point recording format. I have tested it with the Zoom and on connection, the '32-bit float' text lights up already on the device, before starting any app. This makes sense since there are no system audio settings like on OSX, so iOS will just choose the 'USB alt setting' with the highest resolution. In AEMS, I can see recording values above 0dB and they are retained on playback (when you choose the new 32-bit float mode). I also added 32-bit float support in the custom USB audio driver for AEMS on Android.

    Hmmmm not sure on this

  • solncekreezesolncekreeze

    Can you tell me if F3, when connected to an ipad or iphone, can record both to a card and to an iphone/ipad?

  • raabjeraabje

    Talk about new, there comes a R4, little multi track recorder, that also works as an interface.

    https://zoomcorp.com/en/de/digital-mixer-multi-track-recorders/multi-track-recorders/r4-multitrak/

    That one has my interest. No midi and only a few inputs, but you get a small recorder as a bonus.

    I think you have to power it up through an USB hub, or with batteries for IOS, just like the R8 recorder.

    I have got the R4. Works fine with Ipad, although limited to 48khz sample rate. I use Eneloop rechargeable batteries in the R4, that should give me approx. 6 hours operation time.

    Idea is to create backing tracks on the Ipad and copy the files to the R4 and record my guitar on the recorder. Or use the R4 as an audio interface for Ipad.

    It is a nice small device, and there are guitar EFX inside, same as the Zoom multi effects but only with 2 parameters to adjust. And there are click tracks and drum loops inside, the R4 is perfect already as a stand alone device.
