Audio parameters

Audio Bitrate:

Audio bitrate is a key determinant of audio quality and file size, measured in kilobits per second (kbps). Common bitrate values range from 128 kbps, suitable for standard quality, to 320 kbps for high-quality audio. In professional settings, bitrates can be even higher. Our tool allows you to choose from a variety of bitrate options, enabling you to strike the perfect balance between sound quality and file size based on your specific needs, whether it's for casual listening or high-fidelity audio playback.

Sample Rate:

The sample rate, measured in hertz (Hz), defines how many times the audio is sampled per second. Standard CD-quality audio uses a sample rate of 44.1 kHz, while professional audio recordings often use 48 kHz or higher, up to 192 kHz for high-resolution audio. Our conversion tool lets you adjust the sample rate to suit your requirements, offering the flexibility to choose between standard quality for everyday use and higher rates for detailed, professional-grade audio production.

Introduction to M4A Format
