BASS Function Library (Sound and Music Functions)

BrettF · October 29, 2008

BASS Function Library

This library is a wrapper for the powerful Bass.DLL and add-ons (which increase the functionality of Bass.DLL). Bass.DLL is ideal for use in your applications and scripts if you want an easy way to play a vast range of music and sound files formats while keeping dependency on just Bass.dll and it's add-ons (which in turn maximizes compatibility and minimizes extra requirements for your software to run.), while retaining a small file size.

The UDFs included with the release are:

Bass

The basic Bass library. Required with all (most) add-on libraries. Provides playback of many sound files (and streams).

BassASIO (By eukalyptus)

BASSASIO is basically a wrapper for ASIO drivers, with the addition of channel joining, format conversion and resampling.

BassCD

Allows for digital streaming and ripping of audio CDs along with analog playback support.

BassFX (By eukalyptus/BrettF)

An extension providing several effects, including tempo & pitch control.

BassEnc (By eukalyptus)

An extension that allows BASS channels to be encoded using any command-line encoder with STDIN support (LAME/OGGENC/etc), or any ACM codec. Also features Shoutcast and Icecast stream sourcing, and PCM/WAV file writing.

BassSFX

Provides a complete set of functions to include support for winamp, sonique, bassbox, and Windows Media Player visualization plugins.

BassTags

Provides a simple way to retrieve ID3 tags from stream handles.

BassCB/Bass_EXT (ProgAndy)

This is for advanced users. BassCB allows the playback of streams in AutoIt.

BassVST

Allows use of VST effect plugins.

Download

The download includes all of the wrapper and constants, the original download, examples for all of the previously mentioned add-ons, sample audio files (6 channel audio files also included), sample visualization plugins for BassSFx and more.

Great example of visualisations using bass.dll:

Thanks to monoceres.

Great! I recommend to rename _PtrStringRead to __BASS_PtrStringRead So there are no errorrs, if another UDF incudes those function, too

Was the header info for those functions correct? I basically made it up from what I understood about it... :idea:

ronriel · October 29, 2008

This is very interesting!

Thank you.

Well, most ist correct

Here the corrected headers:

_BASS_ChannelBytes2Seconds()... "uint65" ???

_BASS_ChannelGetPosition()... change return type from "uint64" to "udword"

~~This is confusing me, cause it never works for me (setting position.) I have something working, but its not updating the position?~~

EDIT: Worked it out! Will update bass.au3 soon, and add another example of getting and setting the position!

Hi

How do I get the name of a recordingdevice?

_BASS_RecordGetDeviceInfo returns only: 0x00144328

thx

E

BrettF · November 2, 2008

Made a mistake. How does this go for you?

Example

;Get Recording Device Information.
#include <Bass.au3>
#include <BassConstants.au3>
#include <Array.au3>
$bass_dll = DllOpen("BASS.dll")

$return = _BASS_RecordGetDeviceInfo($bass_dll, 0)
_ArrayDisplay ($return)

Function

; #FUNCTION# ====================================================================================================

; Syntax.........: _BASS_RecordGetDeviceInfo($bass_dll, $device)
; Parameters ....:  -   $bass_dll   -   Handle to opened Bass.dll
;                   -   $device     -   The device to get the information of... 0 = first.
; Return values .: Success    - Returns an array containg the device info.
;                                   - [0] = Name

works fine :mellow:

big thx!

BrettF

Great job! Thank you for sharing! :mellow:

BrettF · November 3, 2008

Thanks!

First post will be updated soon when I get round to it... I might make a new example based around Monoceres' work on visualisations. They really do rock!

Cheers,

Hi

I´ve tried to write an UDF for bassenc.dll

bassenc.dll is used to write audiodata to disk, send to an encoder (lame.exe...) or stream to an icecast or shoutcast-server.

bassenc.rar

there are 2 examples (simple wav/mp3 recording scripts) included:

example_callback.au3

example_no_callback.au3

why?

because there are problems...

if you use _BASS_RecordStart without a CallBack then you´ve to call _BASS_ChannelGetLevel at least once in the specified $BASS_CONFIG_REC_BUFFER-time otherwise no data is sent to the encoder!?!

This example is stable, but if you are moving the GUI during encoding, no _BASS_ChannelGetLevel is called and the recordingfile has dropouts.

_BASS_RecordStart with a CallBack sends all recorded data to the encoder, but the callback procedure crashes the script after a while!

can this be fixed?

I hope you understand my bad english :mellow:

Eukalyptus

by the way:

I found 3 bugs:

line 218: "_BASS_SetConfig"

________^ underscore

line 1092: " BASS_Get3DFactors"

_________^ space

_BASS_RecordStart: if you don´t use a callback ("") then error @ DllCallBackRegister

I will take a look at the BASSENC, but I'm confused about the first 2 bugs... Number 3 makes sense

EDIT

Nice work on BASSENC! It looks nice and works very well. I've started to get BASS_Video in the works as well. I'd say it might be easier to use an ADLIB loop? See how that goes. Its nice to see people expanding on the original UDF to start to utilise the many other BASS_*.dll's. Nice work! :mellow:

Cheers,

Brett

...but I'm confused about the first 2 bugs... Number 3 makes sense

wrong dll-function names:

DllCall($bass_dll, "int", "_BASS_SetConfig"...

the functionname in bass.dll is "BASS_SetConfig" without the first underscore. (copy & paste *g*)

---

Because of the crashing callback, I wrote a dll in freepascal some time ago, including the basic functions I need to record audio.

Do you think that it´s possible to write a dll with the function _Bass_RecordStart incl. callback and do all the other things in AutoIt?

The problem is, that the dll and AutoIt have to use the same instance/handle of bass.dll !?

c.u.

BrettF · November 4, 2008

Ah I see now. I've fixed them, will update some time soon.

Can't write DLLs in AutoIt. :mellow:
