1. Therefore, most hi-fi loudspeakers employ multiple drivers to cover the audio spectrum satisfactorily. 2. The cutoff frequency can be anywhere in the audio spectrum . 3. Narrowband is also used in sending audio spectrums that consume a restricted range of frequencies. 4. Inspection of the audio spectrum using a spectrum analyzer often provided significant clues to the scrambling technique. 5. Full-range drivers have a single acoustic center, and can have relatively modest phase change across the audio spectrum . 6. It allows, for example, to visualize raw sound data, to use filters or to show the audio spectrum . 7. This comes at the expense of the satellite speakers, which provide the high-and midrange parts of the audio spectrum . 8. Techniques he uses to analyze the acoustic properties of violins include audio spectrum analysis, density testing, and materials modification. 9. For the audio spectrum , you can use software on a PC in conjunction with your sound card to create a spectrum analyzer. 10. An example of this is their electrical impedance, which varied across the audio spectrum by a ratio of more than 100 : 1.
