Input: Read this: Other types of lossy compressors, such as the linear predictive coding (LPC) used with speech, are source-based coders. These coders use a model of the sound's generator (such as the human vocal tract with LPC) to whiten the audio signal (i.e., flatten its spectrum) before quantization. LPC may be thought of as a basic perceptual coding technique: reconstruction of an audio signal using a linear predictor shapes the coder's quantization noise into the spectrum of the target signal, partially masking it.
Question: What is thought of as a basic signal coding technique?

Output: unanswerable

Input: Read this: In 1926 Joseph P. Maxwell and Henry C. Harrison from Bell Telephone Laboratories disclosed that the recording pattern of the Western Electric "rubber line" magnetic disc cutter had a constant velocity characteristic. This meant that as frequency increased in the treble, recording amplitude decreased. Conversely, in the bass as frequency decreased, recording amplitude increased. Therefore, it was necessary to attenuate the bass frequencies below about 250 Hz, the bass turnover point, in the amplified microphone signal fed to the recording head. Otherwise, bass modulation became excessive and overcutting took place into the next record groove. When played back electrically with a magnetic pickup having a smooth response in the bass region, a complementary boost in amplitude at the bass turnover point was necessary. G. H. Miller in 1934 reported that when complementary boost at the turnover point was used in radio broadcasts of records, the reproduction was more realistic and many of the musical instruments stood out in their true form.
Question: What happens when frequency decreases in the bass?

Output: recording amplitude increased

Input: Read this: During the Reformation, the term was hardly used outside of the German politics. The word evangelical (German: evangelisch), which refers to the gospel, was much more widely used for those involved in the religious movement. Nowadays, this word is still preferred among some of the historical Protestant denominations, above all the ones in the German-speaking area such as the EKD. The German word evangelisch means Protestant, and is different from the German evangelikal, which refers to churches shaped by Evangelicalism. The English word evangelical usually refers to Evangelical Protestant churches, and therefore not to Protestantism as a whole. It traces its roots back to the Puritans in England, where Evangelicalism originated, and then was brought to the United States. The word reformatorisch is used as an alternative for evangelisch in German, and is different from English reformed (German: reformiert), which refers to churches shaped by ideas of John Calvin, Huldrych Zwingli and other Reformed theologians.
Question: Name two contributors to Reformed churches.

Output: John Calvin, Huldrych Zwingli

Input: Read this: In 1978, Josep Lluis Nunez became the first elected president of FC Barcelona, and, since then, the members of Barcelona have elected the club president. The process of electing a president of FC Barcelona was closely tied to Spain's transition to democracy in 1974 and the end of Franco's dictatorship. The new president's main objective was to develop Barcelona into a world-class club by giving it stability both on and off the pitch. His presidency was to last for 22 years, and it deeply affected the image of Barcelona, as Nunez held to a strict policy regarding wages and discipline, letting go of such players as Maradona, Romario and Ronaldo rather than meeting their demands.
Question: What group elects the club president?

Output:
members of Barcelona
