WAV (Waveform Audio File Format) is a lossless audio format developed by Microsoft and IBM. It preserves the original audio data without any compression, resulting in high-quality audio.

MP3 (MPEG-1 Audio Layer 3) is the most widely used lossy audio format for streaming music. It uses perceptual coding to remove inaudible parts of the audio signal, resulting in smaller file sizes while maintaining acceptable audio quality.

FLAC (Free Lossless Audio Codec) is a lossless audio format that preserves the original audio data without any compression. It is commonly used for high-resolution audio, where preserving the original quality is crucial.

CD-quality audio typically uses a sampling rate of 44.1 kHz, which means that the audio signal is sampled 44,100 times per second. This sampling rate is sufficient to capture the full range of human hearing.

DTS (Digital Theater Systems) is a lossless audio format commonly used for surround sound in movies and home theater systems. It provides high-quality multi-channel audio with support for up to 8 channels.

A 16-bit audio file has a bit depth of 16 bits, which means that each sample in the audio signal is represented by a 16-bit integer. This allows for a wide range of possible values, resulting in higher audio resolution and dynamic range.

FLAC (Free Lossless Audio Codec) is a lossless audio format that uses compression to reduce the file size without compromising the audio quality. It is commonly used for archiving and preserving audio recordings in their original quality.

The MP3 audio format supports a maximum bitrate of 320 kbps. Higher bitrates result in better audio quality, but also larger file sizes.

AAC (Advanced Audio Coding) is a lossy audio format commonly used for streaming high-quality music on platforms like Spotify and Apple Music. It provides good audio quality at relatively low bitrates, making it suitable for streaming over the internet.

Metadata in digital audio files contains information about the audio file, such as the title, artist, album, genre, track number, and other relevant details. This information is used by media players and other software to organize and display audio files.

WAV (Waveform Audio File Format) is commonly used for professional audio production and editing due to its lossless nature and wide compatibility with audio editing software. It preserves the original audio data without any compression, ensuring the highest possible audio quality.

The Nyquist frequency is the highest frequency that can be accurately represented in a digital audio signal. It is equal to half the sampling rate. Sampling at a rate higher than the Nyquist frequency is necessary to avoid aliasing, which is the distortion of high-frequency components in the audio signal.

DTS (Digital Theater Systems) is a lossless audio format commonly used for multi-channel audio in home theater systems. It supports up to 8 channels of audio, providing a more immersive and realistic surround sound experience.

Dithering is a process used in digital audio processing to reduce quantization noise. Quantization noise is a type of distortion that occurs when an analog audio signal is converted to a digital signal. Dithering adds a small amount of random noise to the audio signal before quantization, which helps to mask the quantization noise and make it less audible.

FLAC (Free Lossless Audio Codec) is a lossless audio format that is commonly used for storing and archiving audio recordings in their original quality. It uses compression to reduce the file size without compromising the audio quality, making it ideal for preserving audio recordings for future use.
