What exactly is this Icicle all about?

The Icicle is a XLR to USB microphone preamp.

Is the Icicle compatible with Windows 7 and Vista?


Do I need any special software to use the Icicle? Do I need any drivers?

Technically, no. Depending on your application, your OS may have sufficient features to utilize the capabilities of the Icicle. But, to get the most out of your Icicle, you'll want to have some kind of software that allows for digital signal processing and non-linear editing that will accept audio from the USB port. Some examples of these programs are listed below.

Can I use the Icicle with a traditional analog audio mixer?

No. The Icicle features digital output only. It must be connected to a USB port in order to function.

What sample rate and word length does the Icicle use?

The Icicle's digital output is set to 44.1 kHz / 16-bit, just like an audio CD. But this is something that only audio geeks really need to worry about.

How can I select a different sample rate?

Because the Icicle is designed for the greatest ease of operation and setup, sample rate / word length are not user-definable. Sorry, geeks.

Can I use more than one Icicle at a time?

Some audio editing software allows for multiple USB connections. Check with your software vendor-- they should have technical support staff who can answer all of your questions about their product.


Please note: as there are so many different software packages that are compatible with the Icicle, we are compiling a list of software we've tested and assured compatibility. We will publish that list shortly along with detailed instructions explaining how to use the Icicle with each package because, as you can imagine, they are all different! In the meantime, we suggest consulting your software's manual, user forums and technical help lines. Here are a few to get you started:

How to get audio from my Icicle with...

Garage Band

  • Go to Preferences->Audio and select the Icicle as the input device (it will only show up when the Snowflake is plugged in).
  • Create a vocal track and select the icicle as the input device for that track.
  • You may need to adjust the Iciclesf's input level in the control panel if you experience any distortion (crackling).

Logic 7 and Logic Pro 8

  • Open the Audio and MIDI setup program in your Apps->Utilities folder.
  • Create an Aggregate Audio Source (Audio menu - open Aggregate device editor).
  • Add the devices you want to use to the aggregate device (Built in audio and Blue mic).
  • Change the audio device in Logic's audio preferences from Default to Aggregate. (To use an aggregate device with Logic)
  • Open Logic Pro or Logic Express.
  • Choose Logic Pro > Preferences > Audio or Logic Express > Preferences > Audio and select the Devices tab.
  • Select the Device drop down menu and choose the aggregate device from the list.
  • Click Apply Changes at the bottom-right of the window.


  • Select "USB Audio Device" ( 1, in, 0 out) from an audio track.
  • From within that subcategory, there are 3 selections: Left USB Audio Device, Right USB Audio Device, and Stereo USB Audio Device.
  • Select Left or Right for mono audio tracks.
  • Press "R" to arm the track for recording.
  • Roll disk.

Adobe Premiere Elements 4 (Windows Vista/XP)

  • If you should experience any problems getting the program to recognize the mic, Adobe recommends the following: If the device does not allow you to record, then your microphone is not being detected as a valid input device in Premiere Elements. You can use an open source program called ASIO4ALL, which is a device driver that essentially wraps existing WDM devices, like USB microphones, as ASIO-compatible sound devices. Use the following steps to utilize this tool:
  • Quit Premiere Elements.
  • Visit the following web page and download the latest available version of ASIO4ALL: www.asio4all.com
  • Install the software, and restart the system if asked to do so by the installer.
  • Make certain that your microphone is plugged in.
  • Launch Premiere Elements. Go to the 'Edit->Preferences..>Audio Hardware' menu option. For the Default Device, choose the ASIO4ALL option. Click the ASIO Settings button, then select your microphone from the list of devices, click Exit, and then click OK on the Preferences dialog. Close and then restart Premiere Elements.

My Icicle doesn't seem to be working.

Ensure your USB cable is properly connected directly to your computer's USB port. Also check that the status light is illuminated. Open your computer's audio menu and verify that Blue Microphones Icicle is the selected sound source. If that does not help, try restarting your computer, then unplug/replug the Icicle's USB cable.

My recording is distorting.

Decrease the gain by adjusting the gain control knob on the Icicle. Decrease your computers input volume, or try increasing the distance between your microphone and your sound source.

My recording is not loud enough.

Increase the gain by turning the Icicle's gain knob clockwise. Increase your computer's input gain, or try decreasing the distance between your microphone and your sound source.
