So sorry about the Delay.....the last days I have had not so much time...
The New Release will working fine..!!!
Only one Thing a little bit  scraper if the Parameters  of
fThreshold ,fAttacktime,fReleasetime at the Min Values(0.1 - 0.5) Maybe its better to set the MinValues a little bit higher
But i must say the Effekt is very stable
One Question about the Compressor
The FX Compressor will have one Great Effekt if a Audiosong is a liitle bit clipped
with the Active FX Compressor the Clipping is going...is that from the Theory with the DSP Compressor also possible ??

Just wondering am I doing something wrong or is it not possible to count the BPM of a WMA file. returns 0 everytime.

Also, i get a lot of floating point errors with a lot of songs (MP3). Anu ideas

gr. Harold

Hi

Code SelectExpand

var
 BPMHandle : HStream;
begin
  bpmHandle := BASS_StreamCreateFile(false, PChar(FileName), 0,
        0, BASS_SAMPLE_LOOP or  BASS_STREAM_DECODE);
      if (bpmHandle = 0) then
        bpmHandle := BASS_WMA_StreamCreateFile(false,
          PChar(FileName), 0, 0, BASS_SAMPLE_LOOP or  BASS_STREAM_DECODE);
   If BPMHandle <> 0 then begin
     //Do some Stuff
   end;

Greets Chris
about your FloatingPoint Errors Show please the Rest of your Code

@ JOBnik!
I will have here some Problems with the Updated BASS_FX_DSPFX_DAMP
Auto Decreasing The Level will work ...
but
Auto Increasing The Level will not longer work !!!
Do you have change some thing in the Beta Release ???

Hi
The Final Bass_FX.dll will working Fine now
(The Bug in the BASS_FX_DSPFX_DAMP is History 

Good working !!!!!
One Question
BASS_DSPFX_APF (ALL Pass Filter)
It seams that this Filter will have the Same Effect as BASS_FX_DSPFX_REVERB .....
and
BASS_FXDSPFX_LPF (LOWPASSFILTER)
it seams that this Filter will have the same Effect  as BASS_FX_DSPFX_S2M

Hello Jobnik.
I use the code below and the GetPosFloat returns wrong file length in Secs.

Code SelectExpand

Var
   GetPosQword:Int64;
   GetPosDword:Cardinal;
   GetPosFloat:Extended;

 // Free musics
 If BASSAPI_HandleOf_MOD<>0 Then Begin
    BASS_MusicFree(BASSAPI_HandleOf_MOD);
 End;
 // Handle flags for MOD Files
 GenerateFlagForMODFiles:=BASS_MUSIC_CALCLEN or BASS_STREAM_DECODE;

 BASSAPI_HandleOf_MOD := BASS_MusicLoad(FALSE, f, 0, 0, GenerateFlagFor_Files,0);
BASSAPI_HandleOf_MOD := BASS_FX_TempoCreate(BASSAPI_HandleOf_MOD, BASS_FX_FREESOURCE);
                    GetPosDword:=BASS_MusicGetLength(BASSAPI_HandleOf_MOD,TRUE);
GetPosQword:=GetPosDword;
GetPosFloat:=BASS_ChannelBytes2Seconds(BASSAPI_HandleOf_MOD,GetPosQword);

When i Don't use the
BASSAPI_HandleOf_MOD := BASS_FX_TempoCreate(BASSAPI_HandleOf_MOD, BASS_FX_FREESOURCE);
the file length in Secs is calculated correctly.
What's going on? This happens only with HMusic Music files

[(: JOBnik! :)]

Hi

You can get the file length before creating a Tempo stream, or just don't forget that you've to get the length of the original/source handle with: BASS_FX_TempoGetSource(..) function

e.g:

Code SelectExpand

GetPosDword:=BASS_MusicGetLength(BASS_FX_TempoGetSource(BASSAPI_HandleOf_MOD),TRUE);
Have fun!

JOBnik!

OK, thanks a lot.

Hi, 

2 questions:

1- does the BASS_FX_TempoGetSource returns a valid handle if the BASS_FX_TempoCreate was called using the BASS_FX_FREESOURCE flag? From the documentation I cannot find this information.

2- if I call the BASS_FX_TempoGetSource without specifying BASS_FX_FREESOURCE flag, how will the original channel be deallocated?

Thanks in advance and Kind Regards 

Nadia

[(: JOBnik! :)]

Hi

1- does the BASS_FX_TempoGetSource returns a valid handle if the BASS_FX_TempoCreate was called using the BASS_FX_FREESOURCE flag? From the documentation I cannot find this information.

That  flag has nothing to do with the returned value, all it does is to check if the user wants BASS_FX to free the source handle as well when calling BASS_StreamFree function or not, i.e. not freeing the source handle, that has created using BASS_StreamCreateFile(..,BASS_STREAM_DECODE) function, so without that flag you'll have to do it by yourself

i.e:
1. Creating a Tempo stream without BASS_FX_FREESOURCE will only free the handle created with BASS_FX_TempoCreate function.

2. Creating a Tempo stream using BASS_FX_FREESOURCE will free the handles created with BASS_StreamCreateFile and BASS_FX_TempoCreate as well

2- if I call the BASS_FX_TempoGetSource without specifying BASS_FX_FREESOURCE flag, how will the original channel be deallocated?

Are you sure you wrote a right function? I think you meant to write about BASS_FX_TempoCreate? if so, check the explanations above

BASS_FX_TempoGetSource returns the handle of the e.g: BASS_StreamCreateFile function.

@Chris, which effect are you using?

Have fun!

JOBnik!

[nadia]

Hi JOBnik, 

thanks for your answer: I was believing that calling BASS_FX_TempoCreate with BASS_FX_FREESOURCE flag would have caused an immediate free of the original stream decoding channel created using  BASS_StreamCreateFile: instead this flag simply tells to the future call to BASS_StreamFree function to free the original decoding channel and also the resampled channel? Have I understood correctly? 

Kind Regards 

Nadia

 Hi JOBnik
BASS_FX_DSPFX_DAMP,

The curious is that the Crash will not come on the same File sometimes it will crash sometimes not...
After the Crash the Sound will hang in a Endless Loop (Playing the Last Buffers in a Endless Loop)
Greets Chris

I forget
i have no change made on the  Standard Parameters

[MB_SOFT]

Hi JOBnik,
hope you're fine now!!
I'm sorry to bother you with the same problem: i have some file sthat play totally silently when using BASS_FX_DSPFX_DAMP with 16 bit buffers.
Here is an exemple:
http://www.mbsoft.biz/download/radiojingle.mp3
If you try this file in a 16 bit buffer with the following parameters:
.fTarget = 0.96
.fQuiet = 0.01
.fRate = 0.05
.fGain = 1.0
.fDelay = 0.2
you'll hear only silence....
Note that just changing .fdelay to 0.3 it play fine....

Hope you have some time to check calculations in the DAMP source code...
Anyway thank you for your this great fx dll

[Angel]

in order to get the BPM of a file via bass_fx, does the stream has to be a decoding stream? or will a regular stream work aswell?

[big_gun]

Typically a decoding stream works. Don't worry, you can open the same file, once normal, and once for decoding at the same time...

Rick

[big_gun]

Oh, By The Way:

Bass for VB.NET and C# has been updated to reflect the changes in version 2.1.0.1 of Bass_FX.

Download it here http://www.un4seen.com/bass.html#addons

well,i don't want to use a decoding stream next to my normal stream if it isnt really needed, the old bpmf.dll had an example which i used, unfortunatly,using that causes a slight 'hang' in the system while the BPM is being calculated. Another decoding stream next to my normal stream means more resources (altho it wouldnt be much).Reading the bassfx help file,i come to the conclusion that i can get the bpm from a non decoding stream with 'BASS_FX_BPM_CallbackSet', but i migh be mistaken,the helpfile isnt really as clear as the bass helpfile is

Well... think of it the other way around if this flag would free the source handle, then you would hear silence, you know...

You've understood correctly!

BASS_FX_DSPFX_DAMP,

The curious is that the Crash will not come on the same File sometimes it will crash sometimes not...
After the Crash the Sound will hang in a Endless Loop (Playing the Last Buffers in a Endless Loop)

Are you using some other effects as well, Tempo, Reverse or BPM? Because DynamicAMP has nothing to do with BASS_ChannelGetData(..) function. Please send me the dr. watson's debug file or the full debug info, and if you can please send a file that may reproduce the crash

hope you're fine now!!

Thanks getting better

Hope you have some time to check calculations in the DAMP source code...

As I've already said the file is playing fine here and the file before that. It plays fine with 16 and 32 bits.

I've made a loop that starts the sound from 6% and it raised to what I've choosed and no silence at all

My system is: Intel P4 3.0GHz, RealTek 7.1 (onboard) sound card, DirectX 9.0c, WinXP PRO SP2 with latests sound drivers... which system do you have?

Anyway thank you for your this great fx dll

You're welcome and thank you and all who're using BASS_FX

well,i don't want to use a decoding stream next to my normal stream if it isnt really needed, the old bpmf.dll had an example which i used, unfortunatly,using that causes a slight 'hang' in the system while the BPM is being calculated. Another decoding stream next to my normal stream means more resources (altho it wouldnt be much).Reading the bassfx help file,i come to the conclusion that i can get the bpm from a non decoding stream with 'BASS_FX_BPM_CallbackSet', but i migh be mistaken,the helpfile isnt really as clear as the bass helpfile is

1st of all you don't have to use the decoding channel for detecting the BPM, as you've found out you can use BASS_FX_BPM_CallbackSet(..) function. The decoding BPM check is good if you want to check the BPM of a file from that exact point to another with almost no time the other options Callback will only calculate the BPM from the last choosen seconds, e.g. you want to know a BPM every 10 (or else) seconds (you'll get a BPM after the seconds number you've choosed).
I'll see what kind of improvements can I add to the helpfile

Oh, By The Way:

Bass for VB.NET and C# has been updated to reflect the changes in version 2.1.0.1 of Bass_FX.

Download it here http://www.un4seen.com/bass.html#addons

There're still some errors in APIs there I'll send you the list of correction to do

Thank you

Have fun!

Thank you for your reply and tests.
I'm surprised you was not able to reproduce the problem as i'm having the problem to all my users on very different hardware/os systems. Note that the problem occurs when starting play the file from the absolute begin position; if i seek the start position of 1 or 2 seconds then it play fine.
Here there is another "silent" file:

I remarked that the problem occur with files having some gap on top.
Do you have any test application to run on my computer to check the problem?
