You can always convert lossless audio to a lossy format, but you can't convert lossy audio back into higher-quality lossless formats. Lossless formats also allow you to future-proof your audio, should you ever acquire better equipment for listening. That said, if storage space isn't an issue and you have high-quality speakers or headphones, a lossless format might be the way to go. As long as you don't set the bitrate too low, it's unlikely you'll be able to tell much difference between lossless and lossy audio, especially if you're listening on your phone through earbuds. Lossy formats are fine in most situations. Using the Zamzar PPT compression tool, individual (and sizeable) elements - such as pictures and videos - are compressed bringing the overall file size down. All general sounds in Windows, such as when you log in, are in the. The highest quality being th 16-bit at 44,100 HZ, this highest level is the sampling rate of an audio CD and uses 88KB of storage per second. This reduces the overall sound quality, but also makes it a much smaller file and therefore easier on your hard drive. It is not surprising then that there is such a need to compress PPT files so that they do not take up as much storage and can be more easily shared. WAV file extension, 8- or 16-bit samples can be taken at rates of 11,025 Hz, 22,050 Hz and 44,100 Hz. Lossy formats use a lower bitrate, stripping out a good portion of an audio file's data.Lossless formats have all the original data intact and are therefore much bigger files.The first step to reducing the size of audio files is to recognize whether your audio is "lossless" or "lossy". Should You Choose Lossless or Lossy Audio Compression?
