Audio Sounds Tinny During Playback

Symptom #1: Digital Audio File Sounds Tinny or Thin

“I imported an audio file, but it sounds very tinny and thin when I play it back in FCP.”

Background

Digital audio is created by sampling analog audio. The digitizer, be it your DV camera, a DAT recorder, or an audio PCI card, analyzes the level and frequency of the analog audio it has been fed. It looks at each wave and generates binary values to describe them. The number of times per second the audio is measured is referred to as its sample rate. The number of binary values it uses to describe each sample is the bit depth. The more frequently the audio is sampled, the higher the quality and the higher the subsequent data rate. Similarly, the higher the bit depth of the sample is, the more accurately the data describes the audio wave.
