Using DSP allows the use of digital techniques impossible in the analogue domain such as predictive algorithms, thus achieving a flatter frequency response in the audio spectrum and also further reducing noise and other undesirable artifacts when compared to pure analogue systems.

The strong sense of DIY ethics supported by independent street press and community radio stations mostly in Brisbane, Melbourne and Perth forms a breeding ground for creative artists who wish to explore the audio spectrum, as seen in Sticky Carpet rockumentary of Melbourne music scene.

Audio over IP is also used in scientific applications, such as the Neumayer Station in Antarctica, where Barix IP Audio encoders digitize and stream the complete audio spectrum captured by hydrophones under water to the Alfred Wegener Institute for Polar and Marine Research in Germany.

Other budget record labels were Somerset Records that became Alshire Records in 1963, Stereo Fidelity, Audio Spectrum, Peter Rabbit ( children's records ), Azteca, Score Records, a subsidiary of Diplomat Records, a product of the Synthetic Plastics Company who made Peter Pan Records and Ambassador Records.

DAB has also been marketed as having two major advantages over analogue radio broadcasting in that using MPEG-1 Audio Layer II lossy audio compression technology and more recently DAB + using High-Efficiency Advanced Audio Coding, parts of the audio spectrum that cannot be heard by humans are discarded, meaning less data needs to be sent over the air.

Further on in the same article the label explains its decision to release " I Love You, Honeybear " as a double LP : " Due to its length and the wide audio spectrum of the recording, we at Sub Pop, together with Father John Misty, decided that the album sounded much better cut at 45 RPM over 2 pieces of vinyl.

Since the requirements of a full-range driver include both good low and high frequency response ( which are contradictory in terms of physical construction ), a full-range driver is usually limited to covering the audio spectrum above perhaps 100Hz leaving lower frequencies to be handled / augmented by a separate sub woofer or by a special cabinet design for low frequency reinforcement.
38.
Since the woofer covers the lower-end of the audio spectrum and the tweeter covers the upper-end, the dividing point between the two being the crossover frequency, it is of utmost importance that, at the crossover frequency the outputs of both drivers should acoustically sum so as to be seamless, without any peaks or dips, otherwise the loudspeaker is said to " colour " the sound.
