Frequently Asked Questions

We're here to help. Got questions? We have answers!

We’ve just delivered the first batch of Howlers to our backers of our successful Kickstarter campaign and are sold out of extra units in our Webshop as well. We are planning to produce a 2nd batch in Q3/Q4 of 2023. Sign up on our website home page to get notified about the 2nd batch. 

The Super Early Bird price is €99, this price is limited to backers who support the Kickstarter or for those who reserve a Howler before the launch.

Retail price will be €179.

Yes we will ship worldwide from our headquarters in Amsterdam.

You can switch Howler between 2 modes:

a) Recording straight to a swappable microSD-card inside Howler (not included).

b) Livestream with your phone (Android, iOS), or other devices, i.e. laptops (macOS, Windows).

Howler in livestream mode functions as an audio interface and SD-card reader. you can use it to record the audio straight to your phone with help of a recording app, i.e. n-Track Studio and you can copy the recording that you made before.

No, currently Howler’s tech is unable to livestream and record at the same time. However, we do have plans to create an app over 2023 that will be able to do this.

Best Quality – Record in WAV mode: 24 bit/48kHz, recording time is ±3.5 hours straight per file, max 4gb file size, after reaching the max file size, Howler will stop automatically  and start recording to 2nd file (3rd and so on) with half a second of cutoff between the 3.5 hour recordings.
Compact file – Record in mp3 mode: 320 kbps, the max recording length depends on the formatting of your SD card. In FAT32 format, the maximum recording length is 25 hours, using exFAT there is no limit!
If you record with Howler to a recording app on your phone: the quality and file size depend on the storage capacity of your phone and the recording app that you use.

The audio is streamed to your phone as 24-bit, 48 kHz audio. The actual streamed audio format depends on the app that you use.

Yes, Howler is compatible with both iOS and Android.


  • Livestream iOS 13 and higher*
  • File transfer iOS 14 and higher*
* Apple lightning USB adapter needed.
  • USB-C compatible Android phones

We have tested Howler with Twitch, Instagram, Facebook, TikTok and YouTube. Note: on some phones it is necessary to an app such as Lesser AudioSwitch to force Android to use Howler as an audio source.

To livestream with an Android phone, all you need is a USB-C to USB-C cable. To livestream with an iPhone, you will a USB OTG adapter and an USB-C to USB-A cable. We sell the adapter together with the cable as “iOS pack”.

If you want to connect your Howler to a USB-C device, such as an Android phone, or a laptop with USB-C, you only need the USB-C to USB-C cable. Most likely you will already have one at home!

If you want to be able to charge your Android phone while it is connected to your Howler, you need the Android pack which includes an USB OTG adapter and a USB-C cable.

If you want to connect your Howler to your iPhone, you will need the iOS pack. This includes an adapter and a USB-A to USB-C cable. This adapter also allows you to charge your iPhone while it is connected with your Howler.

Yes, Howler is also a standards compliant audio interface and SD card reader and compatible with any laptop.

In general, microSD-Cards with UHS speed class I (U1) only work. However, during testing we have found that some microSD cards are not compatible. If you buy a microSD card via us, you are certain that it will work.

We strongly recommend to (re)format your SD-card as FAT32/FAT.

UPDATE!: SanDisk ‘Pro’ and ‘Ultra’ cards do not work with Howler. 

We have tested with cards up to 256 GB but technically there is no reason why larger cards won’t work. Though you have to reformat your SD-card to FAT32 for 64GB and larger cards. Note: Windows will not allow you to format an SD card of larger than 32 GB in FAT32, use an external tool to format. For macOS users, select FAT format (which is FAT32) in the Disk Utility app.
