Is the BASS_FX_DSPDAMP usable to obtain AGC (Automatic Gain Control)?

For some reason, when I load the effect, very less change appears in the sound. I tried varying with all the parameters - still lacks working like a real AGC.

Hi
don`t mix up AGC with a Compressor/Limiter

The AGC from Jobnik! works fantastic....

By the way the most Real AGC is a Mix of AGC AND Compressor/Limiter

Use both Effects and the Result is perfekt..

Hi,

In bass_fx.pas the "lChannel" param is defined as DWORD. This is an unsigned type, so BASS_FX_DSP_CHANALL (-1) cannot be set. Changing it to a Integer type solves it.

Oops thank you!
BASS_FX.PAS updated and already uploaded

Hi

BASS_FX 2.3.0.1 released

2.3.0.1 - 08/06/2006
--------------------
* New in BASS_FX:
  * Added a valid parameters check for all functions.

* BPM:
  * A little improved Beat position trigger.
  * Changing buffer content won't affect the BPM/Beat detection anymore.
  * BASS_Stream/MusicFree will free the callback BPM/Beat as well.

* BASS_FX.CHM:
  * Added a very simple example to BPMBEATPROC callback, showing how to
    count the BPM with just 2 beats.

* DSP:
  * Fixed small bugs in BASS_FX_DSPFX_VOLUME effect.

Hi

It seems that there's some troubles for VB users, using BASS_FX_DSPFX_SWAP effect
Here's an example using it in VB:

'------------
' SET EFFECT (example with STEREO)
'----------------------------------

Code SelectExpand

Dim info As BASS_CHANNELINFO        ' channel's info (we need number of chans)
Dim fxSwap As BASS_FX_DSPSWAP   ' swap/remap fx
Dim coar() As Long                 ' channels order array (it's dynamic. see below)

Call BASS_ChannelGetInfo(chan_handle, info) ' get number of channels (mono=1/stereo=2/...)

ReDim coar(info.chans) As Long      ' make it dynamic

' set swap effects (change priority as you wish)
Call BASS_FX_DSP_Set(chan_handle, BASS_FX_DSPFX_SWAP, 0)    ' by default it will swap left<=>right

'--------------------------------
' SWAP/REMAP CHANNELS ORDER
'--------------------------------

Code SelectExpand

' left<=>right
coar(0) = 1        ' 0 = left, 1 = right (channels)
coar(1) = 0

' left & right = left
'coar(0) = 0        ' 0 = left, 1 = right (channels)
'coar(1) = 0

' left & right = right
'coar(0) = 1        ' 0 = left, 1 = right (channels)
'coar(1) = 1

fxSwap.lChansOrder = VarPtr(coar(0))        ' return array address (pointer) to BASS_FX
Call BASS_FX_DSP_SetParameters(chan_handle, BASS_FX_DSPFX_SWAP, fxSwap)

'----------------------
' GET CHANNELS ORDER
'----------------------

Code SelectExpand

' make sure you have declared the memory api
Public Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (ByRef Destination As Any, ByRef Source As Any, ByVal length As Long)

' if you want to know the last array order (you have to user Windows API)
Call BASS_FX_DSP_GetParameters(chan_handle, BASS_FX_DSPFX_SWAP, fxSwap)

' copy info from given address (pointer) to our COAR array (info.chans * 4, coz it's Long)
Call CopyMemory(coar(0), ByVal fxSwap.lChansOrder, info.chans * 4)

' Then use COAR as a simple array to check the stored numbers in array :)

BASS_PluginLoad("bass_fx.dll",0)

Gives me:

BASS_ERROR_FILEFORM

Any idea of why?

Hi

BASS_PluginLoad("bass_fx.dll",0)

Gives me:

BASS_ERROR_FILEFORM

Any idea of why?

Yep... the answer is here

[ric]

Ok, i will try by this way. Im coding in PureBasic.

Thanks!!

[yenerich]

Ok, im doing well with BSS_FX

Just one problem with BASS_FX_TempoCreate

Im palying succesfully one song

Code SelectExpand

Handle=BASS_StreamCreateFile(#False, FileName, 0, 0, #BASS_SAMPLE_3D)
BASS_ChannelPlay(Handle,0)

And then try to use TempoCreate to be able to change the tempo

Code SelectExpand

EffHandle = BASS_FX_TempoCreate(Handle,#BASS_STREAM_AUTOFREE)

But get a 100 error return code (its not a valid constant!) and 0 return

I test with different flags and always get same problem.

If i try to use flanger, it does fine

Code SelectExpand

BASS_FX_DSP_Set(Handle,#BASS_FX_DSPFX_FLANGER,FX_Priority)

Any advice?

[yenerich]

I try to follow the VB example, don't hear nothing and app freeze a while

Code SelectExpand

BASS_Init(-1,44100,0,WindowID(0),#Null)

Handle=BASS_StreamCreateFile(#BASSFALSE, FileName, 0, 0, #BASS_STREAM_DECODE)
   EffHandle = BASS_FX_TempoCreate(Handle,#BASS_SAMPLE_LOOP | #BASS_FX_FREESOURCE)

BASS_ChannelSetAttributes(EffHandle,-1,100,-101)

BASS_ChannelPlay(EffHandle, #BASSFALSE)

BASS_FX_TempoSet(Handle,0,0,-100)


Every step gives me BASS_OK

But still don't work. I can't listen nothing and app freezes sometime.

Im missing something?

Hi

Your 2nd post looks fine.
Could you please check if playing a file with precompiled C examples (C\BIN) plays fine?

[yenerich]

Thnaks for your reply:

Yes, C binary sounds fien and do the job.

I found that if i change the pitch from -100 to 0 it stops freezing, BUT i listen the music but no tempo effect

Code SelectExpand

BASS_FX_TempoSet(Handle,100,0,0)

No matter which value i pass to tempo, i don't listen the change but if i get using BASS_FX_TempoGet i get the value i set (lets say 455) as tempo value but that dosen't menas that i listen any tempo change (like i listen using the C binary in your examples).

My code

Code SelectExpand

Handle=BASS_StreamCreateFile(#BASSFALSE, FileName, 0, 0, #BASS_STREAM_DECODE)
   BASS_SetVolume(100)
   Handle = BASS_FX_TempoCreate(Handle,#BASS_SAMPLE_LOOP | #BASS_FX_FREESOURCE)
   
   BASS_ChannelSetAttributes(Handle,-1,100,-101)
   
   BASS_ChannelPlay(Handle, #BASSFALSE)

BASS_FX_TempoSet(Handle,500,sampled,pitchd)
Debug BASS_FX_TempoGet(Handle,@tempod,@sampled,@pitchd)
   Debug "Tempo: " + Str(tempod)
   Debug "SampleRate: " + Str(sampled)
   Debug "Pitch: " + Str(pitchd)

As i said, using debugger i saw that the tempo was set fine, and i also receive an "OK" from BASS_ErrorGetText(), buy i listen just a normal play.

*Im using PureBasic.

Thanks in advance!!

Resolved... i was NOT passing values as floats!!

Working fine atm!! 

[Cahyana]

I don't know why, but echo3 not work (VB6). Sorry 4 my bad English. I'm an Indonesian.

Goooooood

Opps... just found a bug in BASS_FX_DSP_GetParameters that would return a wrong lChannel value if using BASS_FX_DSPFX_ECHO3.
Until the new release will be released, please set lChannel param before BASS_FX_DSP_SetParameters

please give me a software name, download link, or an application (preferrably open source) that reduces ambient noises and the like so that we can enhance speech to text accuracy. we will integrate this software for our thesis that involves speech to text. I need a real-time noise reducer, I don't need audacity since it only reduces noise from recorded speech. What i want is a software that reduces real-time noises so as to enhance speech to text. i also encountered some techniques on how to reduce noises like the spectral subtraction but i'm having a hard time understanding it. any other help you can offer?

[yenerich]

Is there any filter in your dll that helps avoiding 'pops&clicks'?

When i set your feature for replay-gain it sounds fine BUT some pops and clicks becomes more audible or maybe was always there and could be nice to filter out.

Thanks in advance!

I didn't look into that noise reduction stuff yet, but an excellent software (not free) that I know that has a very good VST plug-in "DeNoiser" for this is "WaveLab"

Which effect are we talking about?

[yenerich]

Which effect are we talking about?

The one for rasing volume as replay gain. DSPDAM?
