BASS.NET API 2.4.17.7

[BassFan]

that code isnt ready for public!

its to messy and needs more work

since i couldnt get beat data into vis...
i think it was cause of my .net api was the 2.3.1.0 not the 2.3.1.1

ill clean up and make a nicer demo

thanks
mitch

i have say you can not run BassVis 2.3.0.3 with .net api 2.3.1.0 use .net api 2.3.1.1 for this Version
The sample work great with no problem by me

I need to record a audiosource and convert it "on the fly" to several audioformat at the same time (let's say wma, mp3 low bitrate , mp3 high bitrate)  I need create a new file every hour (or different duration) but with out and gap in the recording. I assume that I run Bass recorder all the time and I just create new file every hour.

Plase point me in the right direction on how to do this, "connecting" the encoder correct for this.

Thanks!

*** I think I solved it :-)

[radio42]

Oki - perfect ;-)

[ken]

Well it works as I like encoding several formats at the same time from a live source. But...

How do I set the "EncoderWMA" to encode realy low quality, like 5 kbit/s and 8kHz mono.

I have my recorder at 44.1Khz stereo

Code Select Expand

_recHandle2 = Bass.BASS_RecordStart(44100, 2, BASSRecord.BASS_RECORD_PAUSE, _recProc, 0); and I need it that way cause I encode other formats in good quality.

Code Select Expand

_wma = new EncoderWMA(_recHandle2);
_wma.InputFile = null;
_wma.OutputFile = filename;
_wma.WMA_Bitrate = bitRate;
_wma.WMA_UseVBR = false;
_wma.WMA_UseNetwork = false;
_wma.WMA_UsePublish = false;
_wma.Start(null, 0);

Thanks!

The WMA codec does not support all ranges of samplerates and bitrates.

You might use the "BASS_WMA_EncodeGetRates" method to query the available bitrates for a given samplerate.

[ken]

OK, I see.

Is there any way for me to downsample and go mono before encoding WMA without consuming much CPU and changing the samplerate and for the other encoders I have running on the same channel, "under the same Bass recorder"?

I belived that WMA accepted higher samplerate and downsample it self, I did this with other components some years ago (but they are AciveX so I dont want them here)

[ken]

Old subject..  Is the MP3 a VBR or CBR.

I found this at codeproject, maby something for BASS.Net and the "tag" class. Some extra info like CBR/VBR and VBR bitrates, layer/mpeg type and more: http://www.codeproject.com/audio/MPEGAudioInfo.asp 
or this in VB.NET that not 100% http://www.codeproject.com/vb/net/vbmp3header.asp

I got lost what you are trying to do. ;-)
You want to downsample without changing the samplerate?
-> Downsampling involves changing the samplerate!
-> However, resampling is supported via BASSmix, e.g. change a stream from 44.1kHz to 22.05kHz
-> Same is with going from stereo to mono. This can be done via Matrix Mixing

I belived that WMA accepted higher samplerate and downsample it self

-> Have you tried this with BASSwma already?


Regarding VBR vs. CBR detection:
There is not much what BASS.NET could do, since BASS.NET does not do the actual frame header parsing.
BASS is doing the decoding of MP3 frames and so only BASS could give such information.
However, the issue is, that there is no clear standrad about a VBR header in the frames.
Some encoders write "Xing", some "VBRI" etc.

Hi

Helmut and me have writen a new BassVis Sample for C#_NET
Is the self Sample used in VB_NET, Delphi and VB

here is a shot

and the File only GenBitmap not working to time
you can make it self or wait that Helmut and me have finish it in the next time

i cant get this new demo you made, bassfan, to run...

it says methods missing in the bass_vis.dll

Method not found: 'IntPtr Un4seen.Bass.AddOn.Vis.BassVis.GetWindowLongPtr(IntPtr, Int32)'.

i just downloaded 2.3.0.4 of the .dll
sure enough the new meths arent in that .dll

I guess there is a 2.3.0.5 out there?

you must have .NET v2.3.1.1
or implement your own GetWindowLong from  user32.dll and use 'Const  GWL_HINSTANCE = -6 '

Code Select Expand

TmphInst = GetWindowLong(hWnd, GWL_HINSTANCE)hWnd is the Winhandle from your Form.

this work!

Code Select Expand

BassVis.BASS_WINAMPVIS_Init(BassVis.GetWindowLongPtr(this.Handle, (int)GWLIndex.GWL_HINSTANCE), this.Handle);
with 2.3.0.4
check you have the right .NET API installed

greets

[mitchjs]

I do... IT compiles fine!!

it doesn run, and when i look at the .dll there is NONE of the new exports

the dll size is 74k, its what i just downloaded from the front page here

packed with upx.. shouldnt hurt the exported dll functions...
but they not there...

help file is even old...

maybe send me newest .dll

or attach here

mitch

[BassFan]

check this!
v2.3.0.5 not released yet!

give a feedback if work
greets

[mitchjs]

nope...

this method is not in 2.3.0.5

.GetWindowLongPtr(IntPtr, Int32)

maybe its not susposed to be, and the demo is bad

cause its in the .net api

but the other NEW methods are there

mitch

[BassFan]

nope...

this method is not in 2.3.0.5

i have checked it for 3 min and it work fine...
the self DLL.. self Sample what i have upload

this methode

Code Select Expand

GetWindowLongPtr(IntPtr, Int32) is in .NET API not in BassVis self 

greets

[mitchjs]

ok, then bug in .net api

here is the line

BassVis.BASS_WINAMPVIS_Init(BassVis.GetWindowLongPtr(this.Handle, (int)GWLIndex.GWL_HINSTANCE), this.Handle);

and it compiles fine

mitch

show the pic what i have upload

sorry, i did not read it right

Add audio to a audiofile?

How do I easiest and fastest open a MP3 file and add one seconds silence at the end of that audiofile and save it, preferly without any extra compression and loosing quality?

Thanks!

[radio42]

Without any recompression etc. you need to open the MP3 file yourself and add the sample data according to the MPEG specs. However, there is no such raw method in BASS or BASS.NET...

[ken]

ok thanks, and if I open and reencode the file with BASS.NET how do I add the extra second of silence at the end?
