Obtain the most tiny audio file with a MP3 [Resolved]

[Kwai chang caine]

Yes i have understand now...
But i want use directly the encoder with PB.
So i can make a runprogram of OGGENC like the FFMPEG

I have see, on your great link also the MPC enc..perhaps it's the same things

Thanks, i try all that
I wish you a good day

Hi KCC,

I use this encoder in one of my tools via the commandline. However the tool is for Mac OS X, but the command-line itself should be the same...
If you like, I will have a look this evening, how I did this. Means, when I get home, and provide an example.

Thanks a lot JAMIROKWAI

Because with all this parameters, i don't know exactely what parameters, i must use, for create mono and better tiny sampling for obtain the more little file

Hiya,

I made my code into something more general... Here you are.
With the options used for ConvertToOgg, this shrinked a 130k file to 6k... Your results may vary.
The Input has to be .wav, I think... My OGGEnc-File (for Mac OS X) was made by Michael Smith of XIPH.

Code: Select all

; Code to convert a test.wav to test.ogg using oggenc
; you may us this snippet however you like, but please give credit :)
; (p) 2009-2010 quadWorks.de

#Quality  = 3   ;   3 is Standard, 0 worst, 10 best quality
#minBits  = 80  ;  80 is Standard, 16 is worst, 384 is best
#maxBits  = 128 ; 128 is Standard, like above
#varBits  = 128 ; 128 is Standard, like above, if set to 0, then use from #minBits to #maxBits
#toMono   = 0   ; 0 = Stereo, 1 = convert to Mono
#toSample = 0   ; 0 = don't downsample, everything else (11025, 22050, 32000, 44100, 48000) downsample
#inName   = "test.wav"
#toName   = "test.ogg"
#Path     = "c:/your/path/"

; this one produces the command line options for oggenc...
Procedure.s ConvertToOgg(inName$, toName$, Quality, minBits, maxBits, varBits, toMono, toSample)
 encode$ = " -q" + Str(Quality)
 If varbits = 0
  encode$ + " -m" + Str(minBits)
  encode$ + " -M" + Str(maxBits)
 Else
  encode$ + " -b" + Str(varBits)
 EndIf
 If toMono = 1
  encode$ + " --downmix"
 EndIf
 If toSample <> 0
  encode$ + " --resample " + Str(toSample)
 EndIf
 encode$ + " " + Chr(34) + inName$ + Chr(34)
 encode$ + " -o" + toName$ 
 ProcedureReturn encode$
EndProcedure

; really good quality
;encode$ = ConvertToOgg(#InName, #toName, #Quality, #minBits, #maxBits, #varBits, #toMono, #toSample)
;really bad, but small... : 
encode$ = ConvertToOgg(#InName, #toName, 0, 16, 32, 0, 1, 11025)

; here you have to set the full path to oggenc, and the full path to the working directory of your test.wav and test.ogg
x  = RunProgram(#Path + "oggenc.exe", encode$, #Path, #PB_Program_Open|#PB_Program_Read)
If x <> 0
 While ProgramRunning(x)
  Debug ReadProgramString(x)
 Wend
 If ProgramExitCode(x) <> 0
  Debug "error"
 Else
  Debug "success"
 EndIf
 CloseProgram(x)
EndIf

Thanks a lot JAMIROKWAI

I have try your code

1/ I have put a wave in c:\
2/ I have put OGGENC.exe and the three other file in c:\
3/ I have change the #Path to c:\

And your code return an error

I have see the value of "encode$" and this is the result

Code: Select all

 -q0 -m16 -M32 --downmix --resample 11025 "test.wav" -otest.ogg

Perhaps an error of space with "-otest.ogg" :roll:
I have try this, and nothing better
I have add some chr(34) also...and not better...

Hi KCC,

I tried the above commandline with a Mono-Wave. OGGEnc.exe does not like to --downmix to Mono, when the file already is in mono... (odd, on Mac OS, this worked with the same wave...)

Download the OGGEnc from http://www.rarewares.org/ogg-oggenc.php and rename the oggenc2.exe to oggenc.exe. This worked for me when putting oggenc.exe and test.wav to c:\ with the Original code, BUT using this command:

Code: Select all

encode$ = ConvertToOgg(#InName, #toName, 0, 16, 32, 0, 0, 11025)

.

You see the toMono-Part is 0. The result was the very same file test.ogg.
For #Path, you should use "C:\" then. Probably #toName has to give the full path of the output, e.g. c:\myoggs\output.ogg. I didn't test that.

Last idea: try to use oggenc.exe at the command-line with oggenc.exe -q0 -m16 -M32 --downmix --resample 11025 "test.wav" -otest.ogg

Bonne nuit

Thanks thanks JAMIROKWAI
I moove i moove thanks to you and a friend in french forum also interesting by this subject
I have try directly in command line, and that already don't works

But effectively your code works now, i obtain a file of :

Code: Select all

;encode$ = ConvertToOgg(#InName, #toName, 0, 16, 32, 0, 0, 11025) ; Pour 6 Secondes ==> 65 = 16 K
encode$ = ConvertToOgg(#InName, #toName, 0, 8, 16, 0, 0, 8000) ; Pour 6 Secondes ==> 65 = 11 K
encode$ = ConvertToOgg(#InName, #toName, -1, 8, 16, 0, 0, 8000) ; Pour 6 Secondes ==> 65 = 9 K

1/ 16k to an original file of 64 K in 11025 with q=0
2/ 11K to an original file of 64 K in 8000 with q=0
3/ 9K to an original file of 64 K in 8000 with q=-1

I have two questions again ??
1/ Now, believe you that it's possible to go down more ???
I have try 4000 but that don't works
2/ Believe you it's possible to start with a MP3 ????

Thanks to your help

Bonne nuit

Danke .. gute Nacht zu

Fine

1/ Now, believe you that it's possible to go down more ???

2/ Believe you it's possible to start with a MP3 ????

1. I think, 8000 is the lowest Hz, OGGenc will be able to use.
Smaller is, for that reason, not possible. The smallest is 8000, Mono, 16kbs minRate, and 16kbs maxRate, I think.
2. OGGEnc will only read Raw or Wave, so you have to decode the MP3 first to Wave, and throw the resulting Wave towards OGGEnc

Thanks to your help

You're welcome.

Thanks for all this explanation...
Now that's clear in my mind
I have reach the limit of compression with OGG

I wish you a very good day
