- Since one sample could be anywhere in the bit depth's dynamic range, we need to calculate the audio file's number of bits per second by multiplying its bit depth by the sample rate. We call this "bits per second" value as the audio file's bit rate. We can express bit rate equation as: bit rate = bit depth * sample rate

May 27, 2013 · The bitrate is the number of bits per second. bitrate = bitsPerSample * samplesPerSecond * channels. So in this case for stereo the bitrate is 8 * 44100 * 2 = 705,600kbps. To get the file size, multiply the bitrate by the duration (in seconds), and divide by 8 (to get from bits to bytes):
3 days ago · Audio File Size Calculator. Inputs are bit rate (kbps or kilobits-per-second), audio duration (minutes), and the number of files with about the same duration. Examples of bit rate are: Apple iTunes (standard) - 128 kbps. Apple iTunes (high bit-rate) - 256 kbps.
Jul 10, 2024 · Audio File Size (bytes) = Sample Rate * Bit Depth * Channels * Duration. Where: Sample Rate: The number of samples per second (Hz). Bit Depth: The number of bits used to represent each sample. Channels: The number of audio channels (e.g., 1 for mono, 2 for stereo). Duration: The length of the audio file in seconds.

- What Sample Rate and Bit Depth Should I use?
The sample rate or sampling frequency refers to the number of samples recorded every second. A sample is the signal amplitude, and it contains the information of the amplitude value of the signal waveform over some time. The sample rate is measured in hertz abbreviated as Hz, or Kilohertz abbreviated KHz, where I kHz is equal to 1000 Hz. If you wan...
When audio is sampled, it is stored in bits. This is where bit depth comes into play. The bit depth determines how much information can be stored. The bit depth shows the number of possible amplitude values in a sample. You can calculate the number of possible amplitude values of a given bit depth. This is done using equation 2 to the power of n (s...
Bit Rate or BitRate refers to the number of bits of processed data over a specific time, which usually means kilobits per second, abbreviated Kbps. For example, if a music track is 320 kilobits per second, there are 320 kilobits of data stored in every second of the track. If a track has a higher bitrate, it will take up more space on your computer...
For sample rate, 44.1 kHz is the best to go with for most music applications. For creating music or other audio for video, 48 kHz is commonly used. A higher sample rate can have advantages for audio professional work or professional music. However, 44.1 kHz remains the most preferred by many professionals. For the bit depth, 16 bits is perfectly fi...
