Yes, CD audio is lossless audio. This means that the audio is compressed without losing any data. This is done using a process called PCM (Pulse Code Modulation).
PCM works by sampling the audio signal at a regular interval and converting it to a digital signal. The sample rate is the number of times per second that the audio signal is sampled. The bit depth is the number of bits that are used to represent each sample.
CD audio has a sample rate of 44.1 kHz and a bit depth of 16 bits. This means that each sample of audio is represented by a 16-bit number, which can represent 65,536 different values. The audio is sampled 44,100 times per second, which is high enough to capture all of the frequencies that humans can hear.
When you play a CD, the digital signal is converted back to an analog signal using a DAC (digital-to-analog converter). The DAC converts the digital signal to a voltage, which is then amplified and sent to your speakers or headphones.
Because CD audio is lossless, the audio that you hear from a CD is the same audio that was recorded. There is no loss of data due to compression.
However, it is important to note that CD audio can still be degraded by other factors, such as the quality of the CD player, the quality of the recording, and the quality of the speakers or headphones.
Overall, CD audio is a high-quality lossless audio format. It is a good choice for people who are looking for the best possible sound quality.
