Hi

You can test the LiveFX example that is in BASS package and change it to use the BASS_FX effects and test.
LiveFX example records sound, applies an effect to it and then plays it in real-time.

[BASS_ErrorGetCode]

Hi

Please check for error code using BASS_ErrorGetCode function.
I'm also not sure if you need (void *)

Hi

I don't see this code above:

       Dim PitchMe As Integer = BassFx.BASS_FX_TempoCreate(stream, BASSFlag.BASS_DEFAULT)
        Bass.BASS_ChannelSetAttribute(PitchMe, BASSAttribute.BASS_ATTRIB_TEMPO_PITCH, 60)

[BASS_STREAM_DECODE]

Hi

Create a stream with BASS_STREAM_DECODE flag if you want Tempo to handle your stream

e.g:
stream = BASS_StreamCreateFile(..., BASS_STREAM_DECODE);

[x86_64]

Hi

OSX package has been updated with support for x86_64 architecture

Hi

With BASS_FX you can change Tempo/Pitch/Speed in Real time and in decoding/encoding as well.
Please check the Tempo example in BASS_FX package to see the demonstration and the code behind the Real time change.

All SoundTouch features are implemented in BASS_FX.

[there's now version 2.4.7.1 is released]

Hi

there's now version 2.4.7.1 is released

2.4.7.1 - 01/07/2011
--------------------
* BASS_FX:
   * Documentation updated.

* DSP:
   * Fixed a small issue in BASS_FXGetParameters for BASS_FX_BFX_VOLUME effect, as it would change the lChannel value
     when the global volume (lChannel=0) is requested.

and to me

[BASS_FX_BPM_BeatDecodeGet]

Hi

Please check in docs or in BPM example from BASS_FX package for BASS_FX_BPM_BeatDecodeGet function

Hi

Until I'll update the OSX package and include there a DSP example, you can look at it in BASS_FX24.ZIP package, that's for windows.

[DSP]

Hi

Please take a look at DSP example that in BASS_FX package.
The same way you have to set any other effect as in example with Phaser and EQ

[BasSample]

Hi

Can you please write the code from Creating the stream to Playing?

i.e:
BASS_StreamCreateFile
to
BASS_ChannelPlay

I see you have more than one hande. e.g: BasSample and Channel?

Are you using Tempo as well?

edit:
You need to play BasSample handle and not the Channel
as I see you are creating an fx with Channel handle

[BASS_STREAM_DECODE]

Hi

Why do you need to use this flag BASS_STREAM_DECODE?
Remove it and I guess you'll start hearing the sound

Hi

This is not the way to calculate the tempo.
The tempo functions in BASS_FX are to change tempo/speed of stream.
To calculate the BPM, use BASS_FX_BPM_ functions.

In your case, you want to calculate the BPM online, then use BASS_FX_BPM_CallbackSet

See docs/examples for more info

[int stream]

Hi

You have 3 streams, but you have only 1 handle for all of them, i.e: int stream
Make an array of stream handles (int stream[3];) and then set volume for each one with the function that Chris wrote above.

One more thing... why are you calling BASS->BASS_Init every time? You have to call it only once when you're loading your application.

[there's now version 2.4.7 is released]

Hi

there's now version 2.4.7 is released

2.4.7 - 07/04/2011
------------------
* BASS_FX:
  * Delphi unit updated: BASS_BFX_ENV_NODE = record, changed to BASS_BFX_ENV_NODE = packed record

* DSP:
   * Fixed bug in BASS_FX_BFX_VOLUME_ENV, being applied slightly early when "bFollow" is enabled.
   * BASS_FX_BFX_DAMP made effect parameter setting a bit more convenient. If fGain < 0 then leave the current value.

* iOS:
   * Added armv7 architecture support.
   * Combined the Device armv6/7 architectures and Simulator libraries into a single file.

Hi

Here's an update 2.4.6.1 beta, that combines support for "armv6/7" architectures and simulator in one file.

Hi

Can you be more specific please?
Which functions return zero?

Did you check the error code?

Hi

Please test with this update:

Hi

JOBnik,

Is there an option in SoundTouch to reset phase at specific points in the timestretching process? I think one of the key differences between this time stretching algorithm and others out there is that others reset phase on percussive transients. This serves to reduce the amount of echo/flamming you hear when slowing down songs. Is there any way to combine beat detection and the phase vocoder to do this? Have you ever experimented with this? If it was possible and had any sort of effect, it would be great to get this option included in BASS_FX.

Here's an answer from Olli:

Phase reset is relevant and necessary in pitch/time shift algorithms that use frequency domain processing,
but SoundTouch does processing in time domain which does not cause drifting of phase response.
