8th July - Make your audio perfect for Youtube, Spotify or Podcasts

5 months ago by Peadar Coyle

Ever wanted to make your audio perfect for podcasts or youtube?

A common requested feature is to make your audio perfect for a certain platforms. Our audio experts have been hard at work on this :headphones: :100:

So we're excited to launch these new mixing features :heart-eyes:

Some customers wanted more control on the loudness off the mixes. Different platforms have different loudness standards so there is now a new parameter in the encoder endpoint. Can be used as follows:

encoder = audiostack.Delivery.Encoder.encode_mix(
  productionItem=mix,
  preset="wav",
  loudnessPreset="podcast"      #spotify, applePodcast, youtube ...
)

Some customers mentioned our voices were a bit harsh (as we were making them loud and excited for advertising). So we implemetned this

mix = audiostack.Production.Mix.create(  
  productionItem=mix,  
  soundTemplate="",  
  masteringPreset="podcast",  
  timelineProperties = {"padding" : 1.5},  
)

Try it out! You'll need to update your AudioStack SDK in Python to v0.0.9

What are the specs?

If you use the following command you'll get back these solutions

audiostack.Delivery.Encoder.list_presets()

"spotify": "-16 LUFS Loudness Integrated and -2 dB True Peak",  
"podcast": "-16 LUFS Loudness Integrated and -3 dB True Peak",  
"applePodcast": "-16 LUFS Loudness Integrated and -1 dB True Peak",  
"youtube": "-14 LUFS Loudness Integrated and -1 dB True Peak",  
"lowVol": "-20 LUFS Loudness Integrated and -5 dB True Peak"

Also to get better user experience, we improved some of our explanations of some of these features - you can see that below. 

"mp3": "mp3 format 320k (320 CBR)", 
"wav": "wav format at 48 kHz sample rate and 16 bits per sample", 
"ogg": "ogg format at 320k", 
"flac": "flac format at 48 kHz sample rate and 16 bits per sample", 
"mp3_very_low": "mp3 lowest quality (~64 kbps VBR)", 
"mp3_low": "mp3 low quality (~115 kbps VBR)", 
"mp3_medium": "mp3 medium quality (~165 kbps VBR)", 
"mp3_high": "mp3 high quality (~190 kbps VBR)", 
"mp3_very_high": "mp3 very high quality (~245 kbps VBR)", 
"mp3_alexa": "mp3 format mono at 48kHz sample rate", 
"mp3_alexa_48br": "mp3 format mono at 48 bit rate and 24kHz sample rate"

We're constantly working on iterating and improving our experience. Let us know what you think.
