I used to enjoy classical music is listening to the CD, so the collection of a lot of CDs and downloaded to the computer Ape and FLAC format music files. As mobile hardware performance (such as battery life, processor speed, sound quality, storage capacity, etc.) and software features (music player management for tracks) improve, you need to consider how to convert these resources into high-quality MP3 files to listen on your phone. This article describes how to implement this functionality base

I. Reasons for writing a playerIn the diagnosis of video conferencing media problems, it is often necessary to take the IP network traffic and form the original code stream for the player to play and diagnose the problem based on the playback effect. This process is generally divided into the following steps: 1) First, use Ethereal to determine whether the RTP stream matches the signaling, such as media type, media Encapsulation Format, and media transport layer address. This step mainly diagnos

Audacity While failing to achieve the same level of commercial success as the other members of the list, I decided to join audacity-a little selfish, and I personally liked it and got quite handy.

CitationI recently had a strong interest in software-defined radio technology (SDR), and I was interested in one of the popular SDR platforms (HACKRF), which received a range of frequencies between 1MHz ~6ghz (wider). There is also a need to mention an interesting and useful attack method, that is, to re-send the attack, of course, it can be understood to record a simple signal, and then broadcast it. I will use my computer to attack and unlock the Jeep Patriot (2006) car. Patriot is a Jeep bran

). Mel Sound Spectrum is a time-frequency meter (time-frequency representation). is obtained from the narrow overlapping window Fourier transform (Fourier transforms) of the audio signal.Each Fourier transform constitutes a frame. These successive frames are then arranged into a matrix, which forms the sound spectrum. Finally, the frequency axis is changed from a linear scale to a Mel scale to reduce the number of dimensions and take a logarithmic scale value.The convolution layer is displayed i

accurately describe the generated phoneme. The sound channel is displayed in the envelope of the short-term speech power spectrum. Mfccs is a feature that accurately describes this envelope. Mfccs (Mel frequency cepstral coefficents) is a feature widely used in automatic speech and speaker recognition. It was developed by Davis and mermelstein in 1980. Since then. In the field of speech recognition, mfccs is an outstanding artificial feature that has never been surpassed ). Well, here we have m

Short-time Fourier transform, short-time Fourier transformation, sometimes called the window Fourier transform, the time window makes the signal only in a certain small interval, which avoids the traditional Fourier transform in the time-frequency local expression ability of the insufficiency, The Fourier transform has the ability of local localization. 1.
