Experimental environment: Computer: Lenovo Zhaoyang k20-80 Notebook Speaker: Harman Cotton Esquire mini Speaker Operating system: Windows RS1 Note : Before connecting a Bluetooth speaker, make sure your computer has Bluetooth enabled. 1, click on the computer on the start-settings, open the System Settings

The auditorium is "a place for listening". This definition implies that all aspects of space, as long as they are related to communication, should be given priority.InSound Reinforcement systemBefore the invention, a large number of people gathered in the auditorium to listen to the speaker without sound amplification speech. The auditorium uses the geometric structure of the room and the sound treatment to provide a natural sound enhancement for the

Most audio experts know that some rooms must have a directed speaker system, and some suggest an omnidirectional speaker system. The final choice of the system will depend on two factors: the location of the Speaker and the internal structure of the room. However, in general, the feedback is directly proportional to the Q aspect of the

GMM-UBM System FrameworkThe original feature was the acoustic feature MFCC, which I did not know very well, except that it was presented directly from WAV or other format voice files.With the feature you can build the model, where our model is called "Gaussian mixture model". The difference between different speakers is mainly expressed in the short-term phonetic spectrum, which can be measured by the probability density function of each speaker's short-time spectral feature. The Gaussian mixtur

How to choose a computer speaker? Computer speakers are one of the most important external devices for multimedia computers, especially those "enthusiasts" players are at any price to buy high-quality speakers, how to buy the speaker of the desirable?

little farther away from the speaker, "scream" will be gone. The distance from the speaker is too close, which is the second reason. The sound of "scream" in different positions is different. The speaker and the string are not in the correct angle, which is the third reason. Different sounds have different "cuts", that is, the frequency of the sound is incor

After the phone APP control speaker is connected to Wi-Fi, the music playing software automatically discovers the speaker, so that you can control the playing of music through the speaker.

Active speakers and passive speakers: Computer speakers are mainly divided into two types of speakers, active speakers and passive speakers. The way to distinguish these two speakers is simple. Active speaker is built with a small power amplifier, directly through the speaker line plugged into the computer's microphone interface, and then the power can be connected to work properly. Passive speakers are ge

When using the computer to play audio, the sound of the speaker is relatively empty, the sound field is more lax. Check the speaker's left and right channel is not reversed, you can put the two groups of audio lines swap position. If the speaker sound is lower, it is important to check the quality of the speaker, the bass

Just equipped with a host, installed USB small speakers, USB plug into the host will have "squeak squeak" of the current sound, very dry people. Mute also have! Once pulled out, it's gone. The "squeak" sound changes as the speaker volume changes. With another power supply to the USB speaker power, the audio cable Connection notebook is not the case! USB speaker
