I'm not a Swift user myself, so unfortunately I can't really help with that, but perhaps this will help?

Need Help.

How to do type conversion ?

Ian @ un4seen · « **Reply #1277 on:** 26 Jun '18 - 14:24 »

I'm not a Swift user myself, so this is just a guess, but how about something like this?

Code: [Select]

let infoPlay = UnsafeMutablePointer<BASS_CHANNELINFO>.allocate(capacity: 1)
...
infoPlay.deallocate()

Hello Ian,

How can use BASS_ATTRIB_TEMPO_PITCH for different voice conversion ?

Ian @ un4seen · « **Reply #1279 on:** 27 Jun '18 - 17:47 »

The BASS_ATTRIB_TEMPO_PITCH value can be set via BASS_ChannelSetAttribute but only on tempo streams, ie. streams created with BASS_FX_TempoCreate (from the BASS_FX add-on).

BASS_ChannelPlay(playStream!, false)

How to get new file path.? i need to send file path to server and play on different platform.

Ian @ un4seen · « **Reply #1281 on:** 28 Jun '18 - 14:50 »

Do you want to get the filename of an existing stream? If so, that is available from BASS_ChannelGetInfo (see the BASS_CHANNELINFO "filename" field).

After this i need to create new file which has this audio effect.

is there any idea to how to do this. ?

Thanks!

You can use the BASSenc add-on to write a new file. For example, to write a WAV file, you can do this:

Code: [Select]

encoder = BASS_Encode_Start(mChanPlay, filename, BASS_ENCODE_PCM, NULL, NULL);

The WAV file will then be written while the original file is decoded/played. Use BASS_Encode_Stop (on the "encoder" handle) afterwards to close the WAV file.

On iOS, you can use BASS_Encode_StartCAFile instead of BASS_Encode_Start for AAC for ALAC encoding. There are also add-ons available for FLAC, Ogg Vorbis, Opus encoding.

i am using this https://github.com/Starling-Inc/Bass.

if i remove this and add manually bass.h and bass_fx.h and bassenc.h than i get this types of error (Use of unresolved identifier BASS_FX_TempoGetSource.)

now what can do for encoding file.?

or
using GitHub link how to load BASSENC plugin ?

It looks like the way they've done it is to append the add-on headers to the BASS.H file, so you could take the BASSENC.H file from the BASSenc package on the BASS page and copy'n'paste it to the end of that BASS.H file. Or perhaps add an #include "bassenc.h" line to the BassPluginLoad.c file instead.

encoder = BASS_Encode_Start(mChanPlay, filename, BASS_ENCODE_PCM, NULL, NULL);

can you describe more .?

Can we encode to wave file without BASS_ChannelPlay .?

Ian @ un4seen · « **Reply #1290 on:** 4 Jul '18 - 17:39 »

Yes. For that you need to create a "decoding channel" by using the BASS_STREAM_DECODE flag in your BASS_StreamCreateFile call, and then repeatedly call BASS_ChannelGetData on it (eg. in a worker thread or timer) until you reach the end.

pgorasva · « **Reply #1291 on:** 5 Jul '18 - 07:03 »

Thanks Ian.

if i remove this line BASS_ChannelPlay(mChanPlay!, false) than my new file is empty.

how to write in file without BASS_ChannelPlay(mChanPlay!, false) .?

Can you help us.? share some example to how to do this.

Ian @ un4seen · « **Reply #1292 on:** 5 Jul '18 - 15:49 »

That sounds like you probably didn't add the BASS_STREAM_DECODE flag to your BASS_StreamCreateFile call. You could do something like this:

Code: [Select]

DWORD decoder = BASS_StreamCreateFile(false, filename, 0, 0, BASS_STREAM_DECODE); // create a decoder for the file
DWORD encoder = BASS_Encode_Start(decoder, outfilename, BASS_ENCODE_PCM | BASS_ENCODE_AUTOFREE, 0, 0); // set a WAV writer on it

// processing loop
while (1) {
	BYTE buf[20000]; // processing buffer
	int r = BASS_ChannelGetData(decoder, buf, sizeof(buf)); // process the decoder (feeds the encoder)
	if (r < 0) break; // reached the end
}

BASS_StreamFree(decoder); // free the decoder (and encoder due to AUTOFREE)

The iOS version of the new BASSenc, BASSenc_FLAC and BASSenc_MP3 releases are up now in the 1st post.

vandenbrakel · « **Reply #1295 on:** 17 Jul '18 - 15:55 »

I'm trying to figure out which (compressed) audio format would use the least cpu with Bass on iOS. I've found out that m4a works better than ogg.

Any wise words on this?

Thanks.

Ian @ un4seen · « **Reply #1296 on:** 17 Jul '18 - 17:16 »

Yes, M4A/AAC files are indeed likely to use less CPU because they can use hardware accelerated decoding on iOS devices. That applies to MP3 too when using the "mp3-free" BASS version.

vandenbrakel · « **Reply #1297 on:** 17 Jul '18 - 18:10 »

Thanks! Very usefull.

Hi all, I'm struggling with MPNowPlayingInfoCenter when using BASS. It doesn't update like play/pause status, playback position...
Anyone has an example that I could follow?

Thanks a lot
