Ich mal die Links zusammengetragen falls es jemand versuchen möchte.
Kenne mich mit bass leider nicht aus.

So ein Forum besteht halt auch nur aus Freiwilligen. Da hat nicht jeder dauernd Zeit einen kompletten Code zusammenzubasteln und ihn hier zu posten.

Hallo an Alle,

ich habe Then ja schon ein sehr tolles Beispiel und eine kleine Erklärung per PN gepostet.

Hier einmal ein ganz kleines Beispiel:

(Die benöigten Dateien (bass.dll, Beispiele und Doku) hat Then schon erhalten.)

Ich denke einfacher geht es kaum noch, oder? Man könnte sich neben der Bass.dll auch mit FFT beschäftigen. Aber muss das sein ?

;
;	BASS v2.4.11.x Windows include for PureBasic v5.31
;	C to PB adaption by Roger Hågensen, 2015-03-23, http://forums.purebasic.com/
;   Modified by Mijikai 2019-01-18 https://www.purebasic.fr/english/
;
;	Changes from last update to the PB include files:
;	Things have been moved around some to make maintenance a little easier.
;	Some of the macros and assert stuff was a little broken, these have been fixed and moved into bass_test.pb
;	BASS_ChannelSetAttributeEx() and BASS_ChannelGetAttributeEx(), BASS_ChannelGetLevelEx() added.
;	BASS_MusicLoad() and BASS_SampleLoad() had the wrong number of parameters, missing freq.l and max.l respectively.
;	Several constants have been added.
;	Special wrappers, file/memory loading macros and prototypes have been removed, definitions/parameters should now match what is in the BASS manual.
;	All Unicode prototypes and compiler exceptions removed, this brings the include closer to the original BASS.h file.
;
;	General changes when porting from bass.h to bass.pbi:
;	As much of the non-Windows platform stuff is kept as possible (iOS, Windows CE, Linux, MacOS) even if PureBasic do not support all those platforms.
;	Windows spesific stuff has compiletime check and inclusion to make the include itself as neutral as possible and match BASS.h where possible.
;  MacOS and Linux alternatives are left where encountered, some fiddling around may be needed though.
;	Any callback definitions are retained but commented out so you can see how they should be made.
;	Some C stuff has been dropped when not needed or an alternative implementation added instead.

;C to PB porting hints:
;PureBasic has no direct match for C like typedefs, just treat these as longs instead.
;TRUE is 1 (#TRUE)
;FALSE is 0 (#FALSE)
;BYTE is a byte
;WORD is a word
;DWORD is a long
;QWORD is a quad
;BOOL is a long
;HMUSIC is a long,	MOD music handle
;HSAMPLE is a long,	sample handle
;HCHANNEL is a long,	playing sample's channel handle

Was ich noch nicht ganz verstehe - es gibt ja eine x86 & x64 Version von bass aber nur eine (PureBasic) 'Header-Datei' !
Bleiben alle Variablen (der Funktionen) und Strukturen gleich ?

Hi Mijikai !

Was ich noch nicht ganz verstehe - es gibt ja eine x86 & x64 Version von bass aber nur eine (PureBasic) 'Header-Datei' !
Bleiben alle Variablen (der Funktionen) und Strukturen gleich ?

Es scheint so.

Also bei der Bass-Include die ich nutze werden eigentlich keine 64 bit Integer, oder andere Speicherfallstricke benutzt.
Auch bei z.B. "Version.a[4]", etc. wurde immer schön auf Kompatibilität geachtet.

Außerdem gibt es ja eine 32 bit bass.dll und eine 64 bit bass.dll .

Und per Standard arbeitet die bass.dll im Ascii-Modus.

Der Unicode-Modus muss erst aktiviert werden. (Dies ist bei heutigen Dateinamen aber dringend empfohlen.)

[Mijikai]

@ccode_new danke für die Infos
Bass sieht scheint eine gute Sound-Library zu sein.
Werde ich mal ausprobieren (bin ein kompletter Neuling was Soundzeugs angeht).

[Mauli]

Man muss aber auch zugeben, dass die Standard MOVIE Behandlung nicht sonderlich gut ist und man deshalb auf was anderes umsteigen sollte. BASS oder FMOD sind da schon toll und umfangreich, aber die Dokumentation ist schon sehr speziell und für Anfänger kaum zu verstehen.

Dieser Code von ccode_new ist schon gut, aber ich habe damit auch nur 2 kleine Linien, welche kaum Ausschlag anzeigen. So wie ich die Sache hier verstanden habe, benötigte THEN ja auch keine PBI oder DLL, die muss er ja schon gehabt haben, sonst könnte er ja die Codes nicht testen. Ich denke, ihm geht's wie anderen auch, dass diese BASS schon recht umfangreich und schwer zu verstehen ist.

Ich bastle auch mal herum, denn ein vernünftiges Beispiel für die verschiedenen BASS Funktionen ist mit Sicherheit hilfreich für jeden, der mit Sounds und MP3s arbeiten möchte

BTW : Selbst der oben stehende Code von CCODE_NEW funktioniert so nicht und bringt Anfänger zur Verzweiflung. Da ist weder was von der BASS.DLL (Load) oder BASS.PBI (Include) drin. Auch etwas, was hier nicht so ganz befriedigend ist. Hier sind laufend nur Codeschnipsel zu finden, die man erst wieder mühevoll zusammensuchen muss. Warum nicht einen Lauffähigen Code ? Im Archiv ist doch auch alles (soweit) lauffähig.

[Then]

@Mauli: Was vergessenw urde zu erwähnen (scheint ja nicht wichtig zu sein) ist, dass du PB 5.62 nehmen musst. Habs mit 5.60 getestet und da ging es nicht..... dünne Linien, warum auch immer.
