What about audition recording?
Now days, audio or video recordings are practically an expectation for competitions and auditions. In many cases a recording is all that is needed, in other instances, it is merly a screening process to so if your student is worth personal audition time. In standard cases, the video capabilities of a digital camera, smartphone, or tablet are up to the task. On the other hand, the audio mic on these devices is typically inadequate. Fortunately, good auxiliary mics for these devices are readily available for reasonable prices.
West Violin Studio has invested in some good quality audio recording equipment. It is available to members of the studio. Non-students may schedule the engineer and equipment for a modest fee. And, the equipment is portable. Contact Nathan at WVS for more information.
