#ADOBE AUDITION COMPRESSOR FOR STREAMING HOW TO#
How to convert an audio file to a different sample rate in Adobe Audition. The main types are FLAC, WavPack, Monkey’s Audio, and ALAC (Apple Lossless). These types of files are generally not used for daily use, but more as a way to store audio.
These file sizes are larger than MP3s – usually cutting the file size in half, instead of reducing it to a tenth of the original. Instead of removing audio, it rewrites data in the file in a more efficient manner. This reduces file size without losing any sound quality. This is referred to a ‘lossy’ compression, where there is some actual loss in sound quality – even if most people can’t hear it.Īlternatively, there is a lossless compression. MP3s are either compressed to 128 kbps or, more common recently, 256 kbps and 320 kbps. This can make any artefacts – or sonic errors – more pronounced. It’s important that you only compress to MP3 once, otherwise a file risks being recompressed. To compress your audio file with Adobe Audition, simply select the MP3 file format when saving. It does this by removing any recorded audio that the human ear can’t pick up. 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. Such files allowed audio to be compressed with little impact on its quality. One option is to compress the file size.Ĭompressing audio has been common practice since the launch of MP3 files. Transferring and working with files this size can be difficult. Sample rate (in hertz not kilohertz) x Bit rate x Number of channels x Number of seconds = total bitsĤ4100Hz 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 bitsĦ,209,280,000 bits / 8 = 776,160,000 bytes or 776 million bytes.
To get a rough idea of how big a file is going to be, you can use these calculations: When dealing with high sample rates, you’re going to end up with large files. Really, it’s only useful for slowing down high-frequency audio.Ĭan I compress an audio file without losing quality? It’s also hard to find computers that can handle it. Some reports have suggested that recording at such a high sample rate can produce issues in your audio, such as jittering. But working at these higher rates could be an issue if your computer can’t handle the added information and storage needed. Similar to 88.2kHz, this sample rate provides more options when mixing and mastering the audio. Using this sample rate produces less distortion (called ‘aliasing’) when converting from analogue to digital, and allows greater freedom when mixing and mastering. This is now the gold standard for hi-res recordings. Do check though, as audio recorded in one rate and played at another will be either sped up or slowed down. This sample rate is also used as a standard rate alongside 44.1kHz.
