Soft do not eat hard food: cheap MP3 improve the sound quality Dafa



General, for a music enthusiast, "Mount Machine" is the symbol of the high state, through its transformation to the machine and the people running at their best. Here, we come together to discuss on the cheap MP3 of "friction" method. First, let's take a look at "hard touch", from hardware to start. But the MP3 hardware circuit is often printed circuit board, to carry out some reform in the circuit seems to us, "rookie" for some very difficult and in addition to a change of headphones, it is generally not the "beloved" in MP3 dismemberment, but for their own MP3 sound quality is too low can not be reconciled. At this time we will enter our theme - "soft Mount." From the literal point of view, we have guessed most of the bar, through the software to improve MP3 sound quality. During the discussion, we first analyze the problem of cheap MP3 hardware. Cheap MP3 first, because cheap, manufacturers in order to save costs, the general use of low-cost decoder chip and components, or amplification circuit, there are a great shrink, resulting in sound quality is not satisfactory, the general weak performance of the high frequency , music is not layered. Although some manufacturers to add some MP3 balanced results, but still sound uncomfortable, contrary to our pursuit of music enthusiasts on the quality of mind, which increases our "soft touch" determination. Our slogan is "definitely the cheapest MP3 make the most pleasant sound issue!" (A joke, they say, you pay for, but to carry forward the spirit of our DIYer, drained the last point potential of MP3! )

MP3 software is divided into two parts: driver and MP3 files. Of course, the driver we are unable to modify your friends, so we start the main from the MP3 file. Write to you, some spectators may have guessed, we are to modify the original MP3 file to make up our hands, the lack of cheap MP3 hardware. How to modify the MP3 of the original document? There are many ways, the author here to tell you I use the program.

I use the software, there are three: Winamp5.0 + Dfx6.4, MP3Trim, Lame3.5. Winamp5.0 + Dfx6.4 is the most important software is mainly used to modify the original MP3 file, and modify stored in the generated wav file; Lame3.5 used to Winamp5.0 + Dfx6.4 generated wav file compression into MP3; MP3Trim the original documents used to increase the Mp3 volume.

Concrete steps are as follows:

1. Configuration Winamp5.0 + Dfx6.4

This is a critical step, will be directly related to the generated MP3 quality. First, open Winamp, drag the song playlist. Open the "EQ equalizer," set in Figure 1. DFX settings then open the panel, set up in Figure 2. Of course, this set is for reference only, we can modify according to their preferences.

2. Generate wav files

Press Ctrl + P to open winamp's "Settings" menu in the "OUTPUT", select "Nullsoft Disk Writer plug-in", which is built-in audio was set winamp plugin, point below the "configuration" into the "configuration menu" Set the output file directory, in "Convert to format" on tick, select "PCM 44.100kHz, 16 bit, stereo," in "Output file mode," select "force wav", point "OK". After confirmation point play winamp key, we need to generate the wav file has been modified. Completed, then the output plug-in set the original "waveOut", will generate the wav file plays out, listen to the sound quality is satisfactory.

3. Suppress MP3

After the test I found to use the lame sound quality from compressed MP3 is the best, but under the lame is a DOS software, for those of us rookie MP3er too difficult. Therefore, the recommended intelligence software produced "lame GUI 1.8", it features mostly lame graphic, very convenient. For the bit rate, I'm using the "average 112 (64k-192k) kBit, 44,000 kHz", the effect was very good, so that the original effect has been a qualitative leap. If you think MP3's sound is too small, you can use MP3Trim to adjust. At this time, we adjust the MP3 of the original document has been completed.

4. Download to MP3 to appreciate

If the results are not satisfied that the first step can be repeated to adjust, until satisfied.

(The above software are available to www.audio100.comm to download.)

In short, after a "soft touch" after the MP3, the sound quality has reached the "completely changed" the point, MP3 effects have greatly improved, for I am not "sensitive" ears, the really can not find and brand MP3 at how much sound quality differences. Think about it, this method is actually to winamp's EQ equalizer and audio plug-in DFX-known integrated into our MP3 of the original file. Of course, this method can also be used in the wma, the effect is not bad. I have since lent the students own MP3 sound quality very good result students feel anger on their own brand MP3 of embarrassing stories to tell. Interested spectators can try the results will definitely not let you down!
