I just want to play my mp3 songs nicely with my car studio...

[tslim]

Hi,

Anyone has experience using one or more of these MP3 utilities:
MP3 Doctor, MP3 Doctor Pro, SuperMp3Normalizer and MP3 Gain PRO. Please kindly share with me your opinions in them.

The below are two of the emails that I have sent to the author (I suppose all the programs are from the same author)

I try Mp3Doctor PRO and I have questions:

Since I can't find single mode in the program:
I have a folder contains about a hundred mp3 files which I want to normalize
and among them there are few (3 of them) that I want to boost the singer's
vocal using the "Equalize" feature (the musical instruments sound too loud).
So how do I normalize all the files and only have that 3 mp3 files processed
with "Equalize" switch ON?

Hi,

I have tried the mp3Doctor Pro with few songs.
I purposely selected songs from my collection with varying volumn (one
particular mp3 song obviously sounds louder than the rest)
It seems that mp3Doctor Pro does not make them even in volumn. A songs which
sound louder than others remain louder after processed!
(Though mp3Doctor Pro's "Equalize" feature works as I have expected)

I am really disappointed for you can't even explain to me what tool should I
buy. I don't mind to buy more than one tools if I really need them.

Here: http://www.mp3doctor.com/buy.html I am presented with screenshot of
MP3 Doctor and MP3 Doctor PRO and I got special offer to buy both Mp3Doctor
PRO and SuperMp3Normalizer together.

Here: http://www.supermp3n...com/screenshots.html I found screenshot
of  SuperMp3Normalizer.

Here: http://www.mp3gain-p....com/screenshot.html I found screenshot of  MP3
Gain PRO which seems to be the same as SuperMp3Normalizer.
and its purchase page http://www.mp3gain-pro.com/purchase.html is offering
me to buy MP3 Gain PRO together with mp3Doctor Pro at a discounted price.

I mean, who in the world should I refer to, to distinguish the different of
the 3 programs. I am serious in getting tools I need, should I instead get
MP3 Gain PRO since I also want to make even all my songs volumn so that I
can play them nicely with my car studio.

I have mix feeling as should I buy a license of one or more of the programs:
1. The program quickly expired after I try it with a few songs... So, I can't really come up with a conclusion about its quality.
2. The websites of the programs are so poorly made. e.g. up to this point of writing, I am still unsure whether MP3Doctor PRO normalize (permanently even out all my MP3 songs volumn level).

Again, please kindly share with me your experience (if any) with the above.

Have you tried Audacity?

http://manual.audaci...tle=Batch_Processing

Probably works as well as many of the paid audio programs.  Also I found, audacity aside, that ripping audio to .wma if your car stereo supports it, can fit more songs on a disc with the same quality.  The same audio that I ripped to .mp3 @320 sounded as good or better ripping to .wma @192.

I'm new to Audacity myself, so I have no expert usage advice. I had some video with horrible audio tracks, as in screeching loud, that I had to tone down.  Audacity did the trick. I just messed around with it with maybe a peek or 2 at the manual.

I have a quite decent model of Pioneer car studio and it supports SDRam (I have a 4G SDRam that can store close to 400 high quality mp3 songs). So, mp3 format is fine for me since I don't have problem with storage capacity.

Btw, thanks for your suggestion of Audacity.

My Google search  produce very few other programs (besides those listed by me and Audacity as suggested by you) that can batch process for my 2 needs:
1) Normalize group of MP3 (I mean even out their volumn level so I don't need to keep adjusting volume knob while driving)
2) Adjust song quality with an Equalizer interface and save it permanently in the MP3 itself.

.. and it supports SDRam

Guess you are talking about an SD card, not SD-Ram, that's totally not compatible with car-audio

(Edit: Added link to SD card wikipedia page)

I use MP3gain (NOT pro - different author!!) which does normalise tracks, but not within a track - but worth noting what the author says when comparing the two apps:

    * "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.

I have had the experience (with mp3gain) that although tracks are normalised, one track will still sound louder or quieter - I presume this is related to the "sound" of the track, but I dont know.

You are right, I mean SD memory card...

My understanding is MP3 Gain writes the value of db adjustment (against a targeted db) in MP3 tag which means:

1. Other song format without a tag like mp3 won't be supported.
2. A player that plays the mp3 must be aware of that tag and is able to adjust volume level accordingly.

I prefer adjustment that is player independent.

tslim, have you tried out the original, free MP3Gain?

that's what I was talking about above skwire - so tslim's post above your's answers that suggestion.

It is very confusing that this MP3Gain Pro used to be called "SuperMp3Normalizer" but borrowed the name from the free version

Doh!     I didn't read your original post carefully enough.   

[MilesAhead]

Another approach may be to drop the files one by one on a player and depending on the sound, move them to folders categorized by the loudness or volume.  Then batch adjust each folder. I doubt any automatic method in any free or low-priced software is going to batch analyze a whole slew of files and bring them into the same ballpark.
