The results of the compression method losing data file size is much smaller, but the quality is reduced. Many of us do not notice the difference when listening to music on a portable music player through headphones small, noisy vehicles for hours, but there is definitely a difference-especially when the rate higher compression ratio encoder (codec) support.
When the MP3 format was developed over 20 years ago, the price of storage devices are very high and personal computer hard disk and 540MB is big - size 2,000 times smaller than 1TB popularity this. Because MP3 files typically 11 times smaller than uncompressed files, we now can store more files than uncompressed audio. We also have the audio format used method of lossless compression (lossless compression) to use this method only slightly reduce the file size without compromising quality.
It may be easier for us to continue to use the MP3 format when copying music from a CD, but to switch to uncompressed audio, then just change a single setting only. Copying process takes less time to perform, because no need to perform the compression process, although you can not store more files in equivalent capacity. If you choose to use methods of lossless compression for mobile music player, you'll still be able to store about 600 songs on a device with a capacity of 8GB.
Here, we will discuss how to make music collection and a small portion is compressed or not compressed at all.
The audio format is
Uncompressed audio formats Waveform Audio is the most common, often simply called WAV. Because only a bit modest amount and frequency of typical quality of this format is nothing more remarkable because no information was excluded. The format other than WAV format can only by achieved the same quality and reduced file size.
Compressed audio format MP3 is the most popular. This format has many options data speeds from 320kbps to 8kbps. For example, the conversion rate of 44.1 kHz and 16-bit depth of the audio CD, the file size will be reduced to 4-176 times. However, due to loss of data compressed so the quality is not as good as uncompressed audio, especially for low-speed data transfer over.
AAC format is a lossy compression similar, although the file size is about two thirds the size of MP3 files of the same quality.
Two methods using compression formats with no data loss or popularity and listen as WAV format is FLAC (Free Lossless Audio Codec) and ALAC (Apple Lossless Audio Codec). The important factor for sound quality conversion speed (sampling rate) and bit depth (bit-depth).
The files are copied from the CD is fixed at a rate of 44.1 kHz and 16-bit, but when you select music for download speeds should choose a higher quality (such as 48kHz, 96kHz or 192kHz with 20-bit or 24 -bit). WAV, FLAC and ALAC are supported on 44.1 kHz/16-bit.
High quality hardware
For years now, people prefer fidelity audio system Hi-Fi component that easily replay as soon as it was born more important, ie CD player or optical drive is more important than the amplification (amplifier) or sound card, and the sound amplifier or sound card speakers more important.
On this basis, if you want to improve the sound quality of music playback from a personal computer, the first is to convert from lossy compression to compress data. Although we accept that this is extremely important, we will also wrong to assume that the hardware is not important. Indeed, if you upgrade the cheap audio hardware is available in most computers, you will see improved sound and better quality.
The best way to listen to high quality sound is the sound from my computer via Hi-Fi high quality, taking signals from as soon as possible factors in the development stages.
However, if you really want to listen to music on your computer, the easiest and cheapest upgrade you can do is buy a better quality speakers. Do not forget the sound card (or chipset) and accompanying sound amplifier; You should also upgrade to the external audio adapter.
How to copy files compressed audio formats with no data loss
Step 1: Either file format is compatible or not depending on which software you use playback, audio hardware may limit the conversion speed. Please download the file from the respective test sites to find out if your hardware can play 24-bit audio at 96kHz and 192kHz speed or not.
Step 2: The test files are FLAC format, not Windows Media Player (WMP) support. Please download and install the VLC Media Player. Try listening to this test files. If no replay is 1 or even 2 files, you will have to use lower switching speed (but still used the method of lossless compression) or to upgrade hardware.
Step 3: Now you can play FLAC files okay, but only in VLC. If you prefer to use WMP, you should download and install the Direct Show filters and codecs K-Lite Codec. Launch WMP and open the template file. Now you can listen to FLAC files in WMP and many other audio formats.
Step 4: Make sure that the FLAC files will not show in your WMP library. To adjust, install the latest updates. Results will vary on several computers. If FLAC files still do not appear in the library, delete all the entries in the library (but do not delete the file) and make the portfolio to WMP.
Step 5: If the WMP still refuses to put the new file into the library, the library may have been corrupted. This can be solved by using corresponding debugger. Type Troubleshooting into the Search box on the Start menu and select 'Troubleshooting'. Choose View All, then select 'Windows Media Player Library'. Follow the instructions.
Step 6: Now you can listen to FLAC files in WMP or VLC. However, you can only have two test files in FLAC format. Shops can download to your MP3 FLAC format, but also other sites dedicated to providing high-bit rate audio, lossless compression. Refer to page nhuhdtracks.com and 7digital.com.
Step 7: There are still quite a few FLAC files to download, but you can copy CD in this format. You will be limited by the depth of 16-bit and 44.1 kHz switching speed of the CD. But using FLAC instead of MP3, you will retain the sound quality of the CD. In WMP, select Tools, Options, then select WAV (lossless) under Format in the Rip Music tab.
Step 8: Copy music from CD in the same way as you are saved in Windows Media Audio format (WMA). If you are creating a new copy with a higher quality of music that you've written earlier by another format, then the implementation would be much easier if you copy them to a different folder.
Step 9: your WAV files can now be played back in WMP in the same way as MP3 or WMA files, and hope you will find the sound quality is improved. However, if you try to figure out the difference, maybe your audio hardware to perform not reached.
Step 10: Before you continue, you should see your WAV files in Windows Explorer. You will see we have a very large capacity. While MP3 files usually has size 2 - 4MB depending on the duration and bit rate, usually the WAV tracks with a capacity of about 40MB. If you prefer to store such large files, please skip to step 14 for instructions on how to record audio lossless compression of yourself.
Step 11: FLAC file sizes are usually about 50% compared to the same WAV file conversion speed, but also hear sound as good. If you want to save space, just convert WAV files to FLAC. Please download and extract the audio converter FlicFlac. No need to install this program, you just need to double click to activate FlicFlac.
Step 12: In FlicFlac, remember to press the button 'to FLAC' and select 'Delete input file'. Click in the text area with the 'Select Files or Drop'. When the window 'Select a file to convert' appears, select the file you want to convert. You should convert multiple files or entire album at once.
Step 13: After finish converting from WAV to FLAC files can you lose information about photo album and singer. If so, right click on the album in WMP library and select "Find album info '. If it is not found automatically, type the name of the album when the Search box appears and select it from the results.
Step 14: Program recordings of Windows Sound Recorder allows you to record high quality audio from a microphone. Click Start -> Control Panel -> Sound, select the Recording tab and select Microphone, and click Properties, then select the conversion rate in the Advanced tab. After recording, please convert WAV files to FLAC format.
