The sq32 reading method refers to the first letter of the five English words Survey, Question, Read, Recite and Review.
Respectively represent the five learning stages of "browsing, asking questions, reading, repeating, and reviewing". This reading method was proposed by Robinson of the University of Iowa in the United States. This method has been highly praised since its creation. The key point is that at this stage of browsing, special attention should be paid to the book's preface (or preface), content summary, table of contents, large and small titles, figures, tables, and photos in the text, as well as notes, references, and Index etc.
：SQ
SQ is an English abbreviation that can mean many things. "SQ" can refer to emotional intelligence, excellent sound quality, circle of death, song title, Internet term "private Q", square root in mathematics, etc. SQ can also be Super Quality in English, which means super quality.
There are many music apps on mobile phones, but the sound quality of a song is often divided into standard, HQ and SQ. HQ is the abbreviation of High Quality in English, which means high quality; SQ is Super Quality in English, which means super quality, which is a kind of almost lossless music.
For music without HQ or SQ logos, it is a standard music type and belongs to lossy compression. By reducing the audio sampling frequency and bit rate for compression, the output audio file will be smaller than the original. The file size is small, so the quality of the songs is average.
Notes on sound quality:
High-quality music such as HQ and SQ is similar to the principle of lossless compression: it can save 100% of all the data of the original file. The size of the audio file is compressed smaller, and after the compressed audio file is restored, it can achieve the same size and the same bit rate as the source file.
Due to the different amounts of information between SQ and HQ, the number of audio tracks and the three-dimensionality of SQ’s presentation are much stronger than those of HQ. When listening to a large arrangement, SQ can enhance subtle hidden instrument sounds and remove noise, which is better than HQ. Therefore, the sound density is different in terms of listening perception, and the sound field is also different.
