Mp3 Gain 4 7 0 8
Changes to MP3Gain 1.3.4 beta: - AACGain support! AACGain is not included in this release, but this version of the GUI is designed to work with it. Download AACGain, rename it to 'mp3gain.exe', and put it in the MP3Gain folder. This app allows you to increase, decrease, and normalize the volume level of MP3 audio files. Simple and easy to use. You can tweak the volume level to make the MP3 louder. This app only works locally without going through the server. You don't need to upload MP3 to any server.
Tired of reaching for your volume knob every time your mp3 player changes to a new song?
MP3Gain analyzes and adjusts mp3 files so that they have the same volume.
MP3Gain does not just do peak normalization, as many normalizers do. Instead, it does some statisticalanalysis to determine how loud the file actually sounds to the human ear.
Also, the changes MP3Gain makes are completely lossless.There is no quality lost in the change because the program adjusts the mp3 file directly, without decoding and re-encoding.
Note about 'Mp3Gain PRO'
The author of MP3Doctor recently renamed his 'SuperMp3Normalizer' program to 'Mp3Gain PRO'.I did not write this new program, so please do not email me any support questions about it.If you're interested, here are the main technical differences between 'Mp3Gain PRO' and my, uh, 'classic'(?) MP3Gain:
- 'Mp3Gain PRO' does volume normalization inside the mp3, not just between separate mp3s. So if you feel a song is too quiet at the beginning (or middle, or end), then it can boost the volume just for that part. Pretty cool, if that's what you need.
- The changes 'Mp3Gain PRO' makes are not undo-able. In order to make its fine-tuned adjustments, it must re-encode the mp3 file.

Just a reminder that the new AAC part of mp3gain is experimental. It's simplynewer, so problems are still being found (and fixed). Use it at your own risk, and I'd suggestbacking up your files first.
10 January 2005
Bug fixed. If you use AACGain with the MP3Gain GUI, make sure you getaacgain version 1.2 or later.
09 January 2005
Well, that was a quick bug discovery ;)
AACGain 1.1 does work with the latest MP3GainGUI, but it incorrectly reports an error even after asuccessful run. Dave is releasing version 1.2 very soon.
Also, Dave and I will hopefully be merging the code in the near future, so AAC support will be completely integrated intoMP3Gain. We'll keep you posted.
08 January 2005
AACGain: Dave Lasker has added AAC support to mp3gain.exe. He wrote aacgain.exe specifically so it wouldwork with the existing MP3GainGUI without too much trouble.
To get it all to work, go download the latest MP3Gain (either '1.2.5 Stable' or '1.3.4 Beta').Then download AACGain. Un-zip aacgain.exe, re-name it to 'mp3gain.exe',and move it into the MP3Gain folder, copying over the existing mp3gain.exe.
That's all you have to do. Now MP3Gain should handle AAC files (.m4a or .mp4).
Please note that aacgain will not work on DRM-encoded files (i.e. music you buy from the iTunes store).It should work just fine with AAC file you create yourself using iTunes, though.
And a technical note for command-line users: As part of coordinating this release with Dave, I've finally fixedthe program return codes in mp3gain.exe to match what everyone else in the world does. So as of version 1.4.6,0 means success, and non-zero means failure.
16 November 2004
Java GUI: Samuel Audet has whipped up a simple java GUI for mp3gain. So for you non-Windows users who want a GUI but can't wait for my initial wxWidgets version, you now have another option. As a reminder, Mac users also still have MacMP3Gain, upon which this new JavaMP3Gain was based.
12 November 2004
Added some new translations: Serbian and an updated Bulgarian.
Also added a new Bulgarian Help file.
02 November 2004
Okay, the workaround mentioned below is out. Version 1.3.2 Beta has it.
Also, I stuck some of the non-unicode improvements into the Stable version. So now Version 1.2.4 is the recommended version for most users.
Also also, there was a bug in the DOS 1.4.4 code. It's fixed. Grab version 1.4.5.
03 October 2004
Argh. I fixed the lower-case naming thing, but apparently in some cases the latest beta version is shortening the file names.
So do NOT use the beta version unless you either
- really need Unicode support,
- want to experiment and help me figure out under exactly what circumstances the file names are shortened,
- or you're feeling lucky
13 September 2004
New 1.3.1 Beta. Someone noticed an annoying bug in 1.3.0: File names were getting reset to lower-case after running MP3Gain on them.
For example, 'HiThere.mp3' would become 'hithere.mp3'.
That bug has been fixed in 1.3.1.
07 September 2004:
Version 1.2.3 is now officially a 'stable' version. Version 1.3.0 is a new 'beta' version.
New features in 1.3.0:
- EXTREMELY limited Unicode support-- basically just enough to get by. Unicode characters in a file name will show up as '?'
- Double-clicking on an mp3 in the list will open it in your default mp3 player. (Right-clicking and selecting 'Play' works, too)
But my frustration with Visual Basic (which is what I wrote the GUI in) has finally reached critical mass.Visual Basic does not like Unicode. Well, it doesn't like displaying Unicode.
So I've decided to start over from scratch. The really cool part is that I'm using wxWidgets, which means I can write the codeonce and compile the GUI for Windows, Linux, and Mac. (Mac users, keep in mind that a MacMP3Gain already exists)
I will also be integrating the back end and the GUI code into a single file. Don't worry, you'll still be able to use the command-line options if you want to, although I'll probably modify the actual parameters themselves so that they make more sense.
Oh, and I did make one tiny addition to the command-line version of mp3gain, which is now version 1.4.4:
If you specify the '-r' parameter ('apply track gain'), then mp3gain skips all 'Album' processing. In previous versions,if you had multiple mp3 files specified in the command line, then mp3gain assumed you wanted to do Album processingon all of the files in the list.
Thanks to Len Trigg for pointing out how this newer method makes more sense, and even suggesting the exact code changes.

Mp3 Gain 4 7 0 8
● Calculation: Amplification (gain) and damping
Mp3 Gain 4 7 0 8 X 8
(loss)as factor (ratio) to the level in decibels(dB) ●
| Gain is the ratio between the magnitude of output and input signals. Gain controls on an amplifier are basically just small potentiometers (variable resistors) or volume controls, that allow you to adjust the incoming signal to the amplifier. |
The amplification factor, also called gain, is the extent to which a device boosts the strength of a signal.
The damping factor, also called loss, is the extent to which a device reduces the strength of a signal.
Enter two values and press the right calculate bar in the line of the missing answer
| The used Browser supports no Javascript. The program is indicated, but the actual function is missing. |
| V1 = Vin and V2 = Vout V2 > V1 or Vout > Vin means amplification. The dB value is positive (+). V2 < V1 or Vout < Vinmeans damping. The dB value is negative (−). V2/V1 or Vout/Vin means the ratio. The amplification or the damping in dB is: L = 20 × log (voltage ratio V2 / V1) in dB. V1 = Vin is the reference. |
In physics, attenuation is regarded as a positive value.
This naturally leads to sign errors when entering numbers.
| 3 dB ≡ | 1.414 times the voltage | (−)3 dB ≡ | damping to the value 0.707 |
| 6 dB ≡ | 2 times the voltage | (−)6 dB ≡ | damping to the value 0.5 |
| 10 dB ≡ | 3.162 times the voltage | (−)10 dB ≡ | damping to the value 0.316 |
| 12 dB ≡ | 4 times the voltage | (−)12 dB ≡ | damping to the value 0.25 |
| 20 dB ≡ | 10 times the voltage | (−)20 dB ≡ | damping to the value 0.1 |
| Using voltage we get: Level in dB: L = 20 × log (voltage ratio) |
| 6 dB = twice the voltage 12 dB = four times the voltage 20 dB = ten times the voltage 40 dB = hundred times the voltage |
If we consider audio engineering, we are usually not interested in power.
Do not ask what power amplification means.
Leave that to the telephone companies or the transmitting aerials (antennas).
Power gain is really not used in audio engineering.
Do we really need power (energy) amplification?
Read the text at the bottom.
| 3 dB ≡ | 2 times the power | (−3) dB ≡ | damping to the value 0.5 |
| 6 dB ≡ | 4 times the power | (−6) dB ≡ | damping to the value 0.25 |
| 10 dB ≡ | 10 times the power | (−10) dB ≡ | damping to the value 0.1 |
| 12 dB ≡ | 16 times the power | (−12) dB ≡ | damping to the value 0.0625 |
| 20 dB ≡ | 100 times the power | (−20) dB ≡ | damping to the value 0.01 |
Using power we get: Level in dB: L = 10 × log (power ratio)
| 3 dB = twice the power 6 dB = four times the power 10 dB = ten times the power 20 dB = hundred times the power |
If you search for the amplification ratio, given the dB value,
then go to the program dB calculation

The voltage is always given as RMS value - but that is not valid for electric power.
There is also the reference power P0 = 1 milliwatt or 0.001 watt ≡ 0 dBm
Level in psycho acoustics as subjectivly perceived loudness (volume)The vague human feeling of the double loudness (volume) is specified
with about 6 to 10 dB. This personal feeling is not an exactly measurable value.
