Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 times per second, each with 16-bit resolution.

Realtek Digital Output就是光线数字输出，跟耳机的插口共用，打开就可以从耳机口输出数字音源，你需要能够接受数字音源的音响设备。

准确来说，杜比全景声（Dolby Atmos）并不是一种音频编码（Codec），而是三种基于对象音频编码的环绕声统称。 它是在TrueHD/Dolby Digital Plus/LPCM音轨的基础上，添加了描述声音信息方位的元数据 (metadata)后的一种封装格式（Format），通俗点就是它是一份基于对象的描述文件，用来描述声音何时在哪个位置出现。 也就是说，杜比全景声其实有3种格式，流媒体用的Dolby Digital Plus内核、蓝光原盘用的TrueHD无损内核，已经XSX游戏主机和Apple TV用的LPCM内 …

Digital audio brings analog sounds into a form where they can be stored and manipulated on a computer. Audacity is a software application for editing, mixing, and applying effects to digital audio recordings. All sounds we hear with our ears are pressure waves in air.

2023年10月31日 · In this post, we’ll walk through the process of exploring and building a model to classify audio recordings from the Audio MNIST dataset. This dataset comprises audio clips where speakers...

For the purpose of storing audio information in digital form, like a compact disc, the normal continuous wave audio signal (analog) must be converted to digital form (analog-to-digital) …

A simple audio/speech dataset consisting of recordings of spoken digits in wav files at 8kHz. The recordings are trimmed so that they have near minimal silence at the beginnings and ends. FSDD is an open dataset, which means it will grow over time as data is contributed.

Since no true digital microphones exist, the analog microphone signal must be converted into a digital representation. This process is known as analog-to-digital (A/D) conversion.

Free Spoken Digit Dataset (FSDD) is a simple audio/speech dataset consisting of recordings of spoken digits in wav files at 8kHz. The recordings are trimmed so that they have near minimal silence at the beginnings and ends.
