before recording the codec of your own learning audio, let's add a bit of hardware knowledgeA series of processors from the 8086 instruction set, known as the x86 processor, 8086 is the oldest 16-bit x86 processor, so the software is labeled I386, indicating that the software is 32-bit, based on the x86 processor , all 32-bit and 64-bit x86 processors can be run (unless the software is marked with a minimum processor limit), x86_64 is a 64-bit extensi

prediction. The principle is to use the past several samples values to predict the current value. The more the past values are used, the closer the predicted value to the actual value. Encode the difference value between the real value and the predicted value, which further reduces the number of quantified bits. There are three models for predicting the current time series value: Ma model-Moving Average Model, AR model-Self-regression model, ARMA model-auto-regression moving average model.

Django view functions often encounter errors similar to 'ascii 'codec can't decode byte 0xef in position 0: ordinal not in range (128. Before resolving the error, you must first understand the difference between Unicode and UTF-8.Unicode refers to a world code table ". UTF-8 is the encoding method stored in this code table. Unicode does not have to be compiled into bytecode storage by UTF-8. You can also use other methods such as UTF-16 and utf-7. At

Previously, we used speex encoding and decoding in applications. Recently, we have summarized the implementation of speex on Android. Speex is an open-source, free, and patent-free audio compression format. The speex project strives to reduce the input threshold of speech applications by providing an alternative high-performance speech codec. In addition, compared with other codec, speex is also suitable fo

Java Implementation BASE64 codecChszs, reprint need to indicate. Blog home:Http://blog.csdn.net/chszsBASE64 and other similar coding algorithms are often used to convert binary data into textual data, which is intended to simplify storage or transmission. In more detail, the BASE64 algorithm is primarily used to convert binary data into ASCII string formats. The Java language provides a good implementation of the BASE64 algorithm, the Apache Commons codec
