Hey! That's not fair! You're not allowed to read my mind! 

Thanks Bernd! That's exactly what I wanted.

Just a question if i can do this with your C# API:

I'm building a Sound to light / Light Chaser controller and i want to controll it from a C# program.

So what i need is

1: Bass beat extractor to trigg the chaser.
2: Sound to light - Volume extraction for four bands : Bass, Middle 1, middle 2, and treble.

Is this possible ?

[radio42]

Yes, I think all you described is possible.
But all that is possible via BASS - BASS.NET is only the C# wrapper ;-)

The only thing which you might find useful in addition is the beat detection via the BASS.NET "Misc.BPMCounter"class, which only exists in BASS.NET...

Regarding the Volume extraction for four bands this could easily be done via BASS_ChannelGetData and receiving FFT sample...some manual analysation is hence still required on your side ;-)

[pern]

Thanks ,

Is the Volume extraction something you are planning ??

Like :  FromFreq - ToFreq  ,  returns: avg value (And Max value? )

[radio42]

It is all there already in BASS...take a look to the FFT data in BASS_ChannelGetData(...)

And you'll have in BASS.NET a "Utils" class with methods which helps you to convert an FFT index to frequency etc.

Does anyone have a simple example of taking a byte[] of wav audio and downsampling from one sample rate to another, changing from stereo to mono ,and outputting to a new byte[] ?

many thanks in advance

[radio42]

For downsampling you might also use BASSMix which supports changing the samplerate as well as converting from stereo to mono (e.g. via the new Matrix Mixing function).

I have now tested the BPMCounter class a little bit, it would be great to be able to:

- Set a fixed release time as an option.
- Select Low Pass detection only.

Any chance for adding these ?

[radio42]

I'll take a look what I can do ;-)

[pern]

Thanks ;-)

If you need beta-testing of it, just let me know.

[pern]

Any news on these ;-)

BPMCounter class:

- Set a fixed release time as an option.
- Select Low Pass detection only.
 

[radio42]

Nop not really.
Was currently buisy with porting all to the new BASS 2.3 version, which will be released soon....

So this could be the next thing to do...but will probably be in a minor version after 2.3 had been released.

Though you're stating in the readme the reasons why you release Bass.NET as a MSI package, I'd really like to just download a ZIP file. Generally, I'm only interested in bass.net.dll, bass.net.chm, and bass.net.xml. I've no need for putting bass.net into the GAC or integration into VS.NET. Being forced to execute a setup and going to the installation folder to get the desired files is really annoying.

It is always a hassle to decide between Pro-Users and New-Users.
And as you might be a Pro-User I can understand your issue.

A non-install would lead to other downsides:
- no integration of the help system into VisualStudio
- no Assembly registration for VisualStudio
- etc.

From a clean development point of view I sill believe it is a clean way to install BASS.NET like it is today - since otherwise I would receive loads of requests on 'how to install' and 'integrate' BASS.NET into projects from the New-Users.

But I'll think about a "slim package" for Pro-Users, which will then only contain:
- Bass.Net.dll
- Bass.Net.xml
- Bass.Net.chm
- No Samples, no Integration, no other Help system

Feature request ;-)

BPMCounter class:

- GetFirstBeatPosition
Very useful if you use calculated beats instead of "live" detection.  Then you know where to start and can calculate every beat position in the song.

- Select Low Pass detection only / more variables inc release time.
Option to set how beat detection works would be great.

How can I record sound from all playing (active) streams into one file?
For examle, I palaying 5 files at the same time and want to write all BASS output (but not any other windows sounds) to one .OGG file. Is it possible, and what classes I have to use?
