The Blue Yeti is compatible with most sound editing software including: AudacityReaper and Sony Sound Forge. The Yeti records at a good quality default setting of 16 bit rate and a sample rate of 48 khz. The analog to digital conversion in the Yeti offers excellent performance with audio sampled at 48 kHz with 16-bits of resolution. The frequency response is full range (20Hz – 20kHz) with a maximum SPL (speaker pressure level) of 120 dB. Microphone Polar Pattern’s Polar patterns are kind of like the shape of the area that a microphone picks up.

The Blue Yeti has four pattern settings. You can quickly change between any of Yeti’s four pattern settings by rotating the pattern selector knob at the back of the mic.

1) Stereo Mode is only ideal for recording music. It captures a realistic stereo image from a variety of sources.

2) Cardioid only hears what’s right in front of it at full volume and other sounds at increasingly diminished volume as the sound source moves further away from the center of the mic. This setting is the most commonly used mode and can be useful in most situations when recording a focused sound source such as an Oral History interview. Cardioid will deliver the most direct, rich sound. It is important to arrange the microphone directly in front of your interviewee and if you want your questions recorded speak up!

3) Omnidirectional hears everything at equal volume from all angles (in a 360 degree sphere surrounding the mic) making it ideal for recording a conversation between multiple parties around a room, a conference call, or any other situations where you want to capture everything in the room. Omnidirectional will also result in picking up more background noise and unwanted hiss.

4) Bidirectional Mode is designed to pick up sound at the front and rear of the microphone, while the sounds to the sides are minimized. The bidirectional setting is very useful in recording an interview with two or more guests.
