48 kHz: How to set it in Android, iOS, macOS and Windows

After creating the 48 kHz Alliance, many people ask me how to set it in Android, macOS and Windows.

After creating the 48 kHz Alliance this year and several prior articles, an increasing number of people now ask me how to set our standard 48 kHz audio sampling rate in Android, iOS, macOS and Windows. Ahead is all of the information, and why to never open GarageBand on macOS, since it silently violates the system without our consent or knowledge and cruelly resets all hardware to 44.1 kHz, damaging the use of other innocent apps. Ahead are more details.

Setting 48 kHz audio sampling in Android

With Android, no system level change is required. Some intelligent Android apps are 48 kHz exclusive, including Hooke Audio Binaural 3D Audio (reviewed here). Other apps allow us to select 48 kHz manually, including:

When connected digitally to a device, the setting in the app (or the app’s 48 kHz exclusivity) commands the external hardware device (i.e. microphone or interface) connected via USB to set its A-to-D (analog-to-digital) converter to 48 kHz.

Sadly, some Android apps are currently stuck on 44.1 kHz and should be avoided until upgraded to 48 kHz capability.

Setting 48 kHz audio sampling in iOS

With iOS, no system level change is required. Some intelligent iOS apps are 48 kHz exclusive, including:

Other apps allow us to select 48 kHz manually, including:

When connected digitally to a device, the setting in the app (or the app’s 48 kHz exclusivity) commands the external hardware device (i.e. microphone or interface) connected via Lightning to set its A-to-D (analog-to-digital) converter to 48 kHz.

Sadly, some iOS apps are currently stuck on 44.1 kHz and should be avoided until upgraded to 48 kHz capability. These include:

  • Adobe Rush (Adobe Rush officialy supports 48 kHz, but makes the initial recording at 44.1 kHz and then upsamples. Cielo de la Paz of the The Storyographist and I documented this in this article. It was later recognized by an Adobe product manager at NAB 2019 in Las Vegas as a bug.)
  • Backpack Studio (whose developer has committed to adding 48 kHz sometime soon, in an email to me)
  • the iOS native Camera app
  • Ferrite
  • GarageBand

Setting 48 kHz in macOS

In macOS, in addition to setting it into the recording app, it is also essential to set the devices to 48 kHz in the Audio MIDI Setup (called Configuración Audio MIDI if your macOS is in Castilian, aka “Spanish”), which is located in the Utilities folder. After you open the Audio MIDI Setup, select the devices from the left column.

In the above screenshot, Dispositivos de audio means Audio Devices.

Then set 48 kHz from the pulldown menu from both the device’s input and output, if it exists. Some devices are in only; others are out only, while many offer both. For best results, do the same with the Mac’s built-in mic and built-in output too.

 

Note that only device’s true hardware capability is shown in the pulldown menu, which is why some devices offer more options than others. For example, the RØDECaster Pro (covered in several articles) is exclusively 48 kHz, 24-bit stereo, so there is nothing to change in the Audio MIDI Setup. In those cases, it’s just displayed information.

Setting 48 kHz in Windows 10

I don’t use Windows at present, but fortunately, Microsoft’s Vanessa Yar documented it for us in 2017:

…follow these steps to get into your speakers Advanced settings:

  2. Select your speaker, then click Properties.
  3. Click the Advanced tab.

  5. You can adjust it according to your preference. Once done, click Apply, then OK.
