Topic: Boost broadcast like ST?

[Ed1966]

Hi friends,

I want to boost the broadcast until level +1 / +2 dB
But what i do the sound is local harder but not at the broadcast site?
I been using Stereotool VST plugin and that is working. But i don't want this.

What am i doing wrong?

I use normalizer and compressor on the stream that i broadcast.
See attachment. Without it's lesser sound.

Regard,
Eduard.

Going ‚above‘ in digital sound processing is not really possible (without cutting of the peaks), eg. there is no headroom (as in the analog world).

StereoTools is a very complex multi-band sound-processor, which manipulates the sound (frequency bands), so that the perceived listening volume sounds louder - its total level shouldn‘t go above 0dB.

Bass itself doesn’t offer anything like ST out-of-the-box.

Ok. There is no possibility FX and so on ?
ST is on the same stream.

Do you mean the broadcast level is lower than the local playback level, and if so, is the encoder/broadcaster set on the same stream that is being played locally? It could be that DSP/FX set on the stream are not present in the encoding/broadcast due to their BASS_ChannelSetDSP/FX "priority" values. They need to be higher than the BASS_CONFIG_ENCODE_PRIORITY setting (-1000 by default) to be present.

[Ed1966]

Yes i think de priority is not -1000
BASS_CONFIG_ENCODE_PRIORITY setting (-1000 by default) to be present.
What is the solution?
The base volume --2000 ?

I don't want to beter than ST but only volume. I have perfect DAMP, COMPRESSOR.

[Ian @ un4seen]

What "priority" values are you currently using in your BASS_ChannelSetDSP/FX calls? Also, which compressor effect are you using, ie. BASS_FX_DX8_COMPRESSOR or BASS_BFX_COMPRESSOR2? If you're using BASS_FX_DX8_COMPRESSOR then you could try BASS_BFX_COMPRESSOR2 instead. Also try raising the effect's fGain parameter if you just want to make it louder.

I have solved the problem.

I was using for extra boost:

Code: [Select]

BASS_ChannelSetAttribute(FMixer, BASS_ATTRIB_VOL, 2.0);
That is not working. I think priority is first and then de NORMALISE and COMPRESSOR restore the sound to 0 dB.
I don't see any priority for normal streams. I don't think it's needed.

I now using:

Code: [Select]

VolHFX := BASS_ChannelSetFX(AStream, BASS_FX_VOLUME, CONST_PRIORITY.BOOST); // set a volume effect on channel
VolumeBASSFXRec.fTarget := ATarget; // pow10(db/20); // boost in dB
VolumeBASSFXRec.fTime := 0.1; // ramping in seconds (100ms)
Result := BASS_FXSetParameters(VolHFX, @VolumeBASSFXRec); // apply the volume effect parameters
CONST_PRIORITY.BOOST is the lowest value and becomes last in line.

Code: [Select]

procedure SetPriority;
begin
  CONST_PRIORITY.CHORUS     := 90;
  CONST_PRIORITY.FLANGER    := 80;
  CONST_PRIORITY.EQUALIZER  := 70;
  CONST_PRIORITY.ECHO       := 60;
  CONST_PRIORITY.LIMITER    := 50;
  CONST_PRIORITY.COMPRESSOR := 40;
  CONST_PRIORITY.BOOST      := 30;
end;
That's working 

I use only stereo so i think 'BASS_FX_DX8_COMPRESSOR' is suitable for me?

Thanks and kind regards,
Eduard.

Ah, that explains it, as the effect of BASS_ATTRIB_VOL would be heard locally but not in the encoding. Using the BASS_FX_VOLUME effect instead will indeed fix that.

I use only stereo so i think 'BASS_FX_DX8_COMPRESSOR' is suitable for me?

Both BASS_FX_DX8_COMPRESSOR and BASS_BFX_COMPRESSOR2 should be fine with stereo, although I seem to recall that the BASS_FX_DX8_COMPRESSOR result was a bit different to the specified parameters.

[Ed1966]

Yes if i tested BASS_BFX_COMPRESSOR2 the hole settings are different. I stick bij my original.
Thank for your effort helping me.
