Yes, sound again

Dec 16, 2019

Hello, I have read through the various discussions as well as the replies from the SL team. Ok, so the advise is to set the compression rate to none, I get it. I also get that SL360  isn't really an audio editor, and it is ok. I have been using narration recorded externally up to now, where I have recorded in wav, then edited in a sound editor, exported as mp3 (yet crisp and clear) and then import to SL360. Reading the discussions I have now learnt that the best settings for SL360 are wav, 16 bit, 44.1 kHz, PCM. I will defo try that the next time around.

But wouldn't it be appropriate to have an option on importing, giving you the option to choose between non compressed/compressed? I find that the compression done by SL makes the sound dull, when the files that I import are great to listen to. Turning off the compression while in SL has next to no affect ... or at least I cannot hear it. So what to do?

Next time I will try the wav-settings, so thanks for that. But my humble suggestion to you is that you upgrade the sound module with the option that I suggest above. Let the default be compressed, cool, but give the option to import uncompressed for those of us who wish to.

Thanks!

Regards,
Bent, Norway

Hello Owen, thanks for responding. As what I make is distributed in a local ethernet, I see no reason but to maximise all settings. So that I do already :-).

I didn't say so in my original message, but can live with it now that I know. But having the option to import sound files with no compression as default (I have already done the routines with regards to compression, eq, noise removal etc. beforehand), would be an ok thing to have. As it is now, I have to set it individually for each sound clip. It would save a minute here and a minute there, not to mention the quality of the sound.

Regards,

Hi Bent,

I appreciate you sharing your thoughts on an option to choose uncompressed audio upon import. I'll be happy to share this with our product team, but feel free to also detail them through a feature request!

As you mentioned, you've read through several discussions and may have seen this, but I wanted to share this article on setting the audio to have no compression with others in the community who haven't seen this option.

If you've set this option and are still having audio issues, feel free to connect with one of our support engineers, and they'll be able to provide tailored support on your audio files!

Ok, thanks. Just a couple of questions.

So if I set the compression to "None" before I begin adding sound files, will I then be able to import throughout the course without having to set it for each and every file I import? If so, that will solve this part of my request.

This is a typical way of working for me: As I progress in my course creation, I import the files I need where I am of whatever I am creating, until finished. Then, when the client wants me to make a change, I may re-record it, do the editing again (with the compression rate I think is appropriate etc.), export it to usually mp3 and then import it to SL360. So far I have only experienced a dulling down of the sound once the files gets into SL360, even with the highest setting on publishing. In the office I record the narration using a couple of methods for record; one portal and one fixed. I use Audacity to edit the files.

The article you linked to says that only mp3 files can be set to non-compression, or else lose the stereo. Why then do you advise us to use wav, 44.1 yadi yadi? Please see the attachment, I snagged from one of the videos you have on your Vimeo page.

Is there a preferred setting for the best mp3 quality import?

I have also used the text-to-speech feature from time to time, which works well sometimes. But it dearly misses an option to slow down the rate of speech. But that will be for another day.

Thanks again,

Bent

Hi Bent!

I can see where making these changes prior to importing the audio would be beneficial for you! As Ren shared, right now changing the compression is a setting offered to mp3 files post-import. 

To answer your second question about mp3 files, Storyline 360 now publishes all audio at 44,100 Hz. This is why we recommend importing similar audio to ensure a seamless publish. I'm having a difficult time nailing down which video that screenshot came from. Would you mind sharing the link?

If your MP3 audio files have stereo sound and you want to keep the stereo format in your published course, turn off compression. Compressed audio has mono sound in the published output.
