discrete time into discrete signals in discrete time. Common quantifiers include: Uniform quantizer, log quantizer, and non-uniform quantizer. The goal of the quantization process is to minimize the quantization error and minimize the complexity of the quantizer (these two are contradictions in themselves ). (A) Even quantizer: the simplest, the worst-performing, only applicable to telephone speech. (B) Logarithm quantizer: it is more complex and easy to implement than uniform quantizer, an

you don't want to upgrade to a new Windows system, you can choose to switch to a different system. In addition to the KO Fu handsome Apple computer is the choice of Linux. Linux is always known for being fresh, trendy, and very safe. In addition you can use some Linux-based depth customization of the system, with the interface and feel similar to XP. For example, Zorin OS or Lubuntu.2, you do not rely on any Windows platform exclusive applicationsSome people's professional needs or hobbies lead

, this is recommended unless the module being imported needs to use sub-modules with the same name from different packages.6.4.2 reference of built-in packages When the package is structured into a sub-package (like the sound package in the example), you can use absolute imports to reference the module of the brother package. For example, if the module sound. Filters. Vocoder needs to use the echo module in the package sound. effects, you can use from

Speech Encoding is divided into three categories:1. waveform EncodingPCM and ADPCM belong to waveform encoding. This encoding method is used to directly quantify each sample point of the waveform, or to compress the correlation between waveforms to remove redundancy and ensure better speech quality, however, the encoding speed is high and the compression speed is small.2. Parameter EncodingSuch as LPC encoding, formant encoding, and Vocoder encoding a

the pitch of the audio while maintaining its length (pitch shifting).variable Speed The speed change can be achieved by the traditional phase sound coder (phase vocoder, an interested friend can read the Wikipedia page). First, the audio is decomposed into overlapping bits, and then the bits are rearranged so they overlap more (which will shorten the length of the sound) or less (the length of the audio will be stretched), as shown in the following

input signal.(2). Audio Source code compilerThe idea of the source code is to attempt to extract the generated voice parameters from the voice waveform signal, and use these parameters to reconstruct the voice through the Voice generation model. The audio source code for voice is called the Sound Code device (vocoder). In the Voice generation model, the channel is equivalent to a filter that changes over time, which is called the variant filter (time

Suppose you want to design a module set (that is, a python package) to process audio files and sound data in a unified manner. Normally, their extensions have different sound formats, such as WAV, AIFF, AU ), therefore, you may need to create and maintain a set of conversion modules between the increasing file formats. In addition, audio data processing (such as mixing, adding echo, and applying the balance function) may be performed. Therefore, you can write a endless stream module to perform t
