Default Some tests on audio export

Hi, guys:

Did some tests of audio export on each of the four formats now available and all seem to be working just fine.

How's that for a report?

As expected, the lossless formats (WAVE and FLAC) seem to exhibit a wider band-width than the MP3 and OGG VOBIS formats, but that's the nature of those formats.

In all, well done with that.

David

Hi David,

Thanks for the report. It's very helpful to know that something does indeed work well. Oftentimes when we include a new feature, or fix a bug (we do in-house testing of course), we stop getting any communication about it from users, and so have to conclude from the lack of communications that the thing works. It's much nicer to have direct confirmation

ttfn,
Sherry

In 3.0.6-116 we have adjusted the mp3 parameters to create a good mp3 export quality.

We have received a report from one of our beta participants that the current parameters work fine for the default soundfonts but some other soundfont like the Timbres of Heaven soundfont result in heavy clippings in the exported audio files. The reason is the different volume of the soundfonts. We work with this beta tester off-line on a concept to be able to have according parameters configurable. We will post more info here in this thread.

Hi friends,

We have run into an item that we want to ask your input about.

With Notation Composer 3, you have the option to use any General MIDI (GM) soundfont that you would like to in the Notation Software Synth. However different soundfonts can have different inherent volume levels, and so there needs to be a way to adjust the Gain for these when listening to a song using different soundfonts, and especially when exporting (rendering) song files to audio files. If the Gain is too high, clipping and/or distortion can occur. If the Gain is too low, then even using the Volume controls may result in unsatisfactory dynamic ranges. Therefore we want to include a Gain Control of some type in Composer so that the user can change this setting easily.

Just to be clear, the File/Export Audio only uses the internal Notation Software Synth for creating the audio files, so this Gain setting only applies to the NS Synth, not to any other MIDI devices.

With the above in mind, where would you as a user look for such a Gain control? Please be specific as this is an important question for the Chief Developer to know where to put the control.

Thanks!
Sherry
