This sample rate is also used as a standard rate alongside 44.1kHz. Do check though, as audio recorded in one rate and played at another will be either speeded up or slowed down.
This is now the gold standard for hi-res recordings. Using this sample rate produces less distortion (called ‘aliasing’) when converting from analogue to digital and allows greater freedom when mixing and mastering.
Similar to 88.2kHz, this sample rate provides more options when mixing and mastering the audio. But working at these higher rates could be an issue if your computer can’t handle the added information and storage needed.
Some reports have suggested that recording at such a high sample rate can produce issues in your audio, such as jittering. It’s also hard to find computers that can handle it. Really, it’s only useful for slowing down high-frequency audio.
Can I compress an audio file without losing quality?
When dealing with high sample rates, you’re going to end up with large files. To get a rough idea of how big a file is going to be, you can use these calculations:
- Sample rate (in hertz not kilohertz) x Bit rate x Number of channels x Number of seconds = total bits
- Total bits/8 = bytes
- Bytes/1,000,000 = megabytes or MBs
44100Hz x 16-bit x 2 channels for stereo recording x 4400 seconds (a 74-minute CD recording) = 6,209,280,000 bits - or around 6.2billion bits
6,209,280,000 bits/8 = 776,160,000 bytes or 776 million bytes
776,160,000 bytes/1,000,000 = 776.16 MB
Compressing the file size.
Transferring and working with files this size can be difficult. One option is to compress the file size.
Compressing audio has been common practice since the launch of MP3 files. Such files allowed audio to be compressed with little impact on its quality. Converting audio to MP3 - which can be done on many computers and some websites - can reduce file size by a factor of 10 in some cases. It does this by removing any recorded audio that the human ear can’t pick up.
