The DisplayPort is a computer port that can transmit audio and video signals without the need for compression. It supports high resolutions and refresh rates while carrying both audio and video simultaneously over a single cable. Additionally, HDMI (High-Definition Multimedia Interface) also transmits both audio and video signals without compression, making it another option for high-quality multimedia connections.
Sound compression refers to reducing the dynamic range of audio signals. It involves techniques that decrease the file size of audio data, making it easier to store, transmit, and stream. Compression can be lossy, which sacrifices some audio quality for smaller file sizes, or lossless, which retains all original audio data.
The purpose is to either listen to audio on a computer without built in speakers or to boost sound
Microwave systems can be used to transmit audio data
Satellite systems can be used to transmit audio data
MPEG
You can use the M-Audio Keystation 88es without a computer by connecting it to a standalone MIDI sound module or a MIDI-compatible keyboard amplifier. This allows you to play the Keystation 88es and produce sound without the need for a computer.
When a PC FM transmitter is plugged into your computer and radio, it will take the audio output from your computer and transmit it through the wire so it will come out of your radio instead of other speakers.
MP3
Unfortunately, I do not think there is a specific length by which wireless audio transmitters transmit and after searching the web for a long time, I have not found anything of it.
A popular type of audio compression format is MP3. It reduces the file size of traditional digital audio files by eliminating some audio data that is less perceivable to the human ear, allowing for more efficient storage and playback of music. This compression enables users to store more songs on their devices without sacrificing significant sound quality. Other common formats include AAC and OGG, which also offer efficient compression.
This is a process which reduces the data rate or file size of digital audio signals. For processes which reduce the dynamic range (without changing the amount of digital data) of audio signals,
as i understand you question u want to record audio in you computer without mic. you can use stereo mix option
