Hello,
I have a very simple question to which I haven't really found a "simple" answer on the forum! :-P
Is an encoding quality of 320 kbps necessarily in CBR or not?
Thank you for the answer! :-)
Have a nice Sunday everyone,

Hello,
I am adding my insight by explaining the terms, knowing that 320kbps and CBR are not related.
320 kbps (kilobits per second) defines the data rate per second, in other words, the amount of information that defines the sound or image (in the case of audio or video encoding).
The more important the bitrate, the better the quality, but it also requires a lot of storage space.
The type of bitrate:
- CBR for Constant Bitrate: ensures that the encoding is fixed regardless of the complexity of the sound or the image.
Point - : If the bitrate is insufficient, it can result in significant degradation during playback (choppy or dull sound, more pixelated image)
Point + : However, it allows for file size control during encoding.
- ABR (Average Bitrate) / VBR (Variable Bitrate): the bitrate is variable and adapted.
In ABR: an average bitrate is defined. If the sound or image demands more or less, it adapts automatically and then returns to the average. This term is often associated with VBR, yet they are different.
In VBR: a minimum and maximum bitrate threshold is defined, allowing the amount of data to vary according to complexity during encoding. These thresholds will not be exceeded, which helps control the file size minimally during encoding.
Point +: ABR allows for maintaining the best audio quality or the best image, even the best fluidity during fast action video scenes. The same applies to VBR, depending on the min and max thresholds (which may result in slight degradation)
Point -: the resulting file from encoding can become large, playback may require more power from the hardware needed to encode or play back, and the synchronization between sound and image is often lost (often unrecoverable delay between sound and image).
It should be noted that 320 kbps is an excellent bitrate for audio regardless of the encoding type CBR, VBR, or ABR.
This bitrate will provide very good quality in MP3 encoding (MPEG-1 Layer III) and even excellent in OGG Vorbis or AAC (MPEG-4), which do not require such a high bitrate for the same quality.
Hoping I have been clear, precise, and concise enough.
Everything comes to those who wait...

Thank you for this information.

Amazing! You answered all my questions without me even asking them. Thank you for taking the time to explain all these details so precisely.
Hello.
CBR = Constant bit rate.
and Kbps = kilo bits Per Second.
If it's Per Second, it's constant.

Hello,
CBR (Constant Bit Rate) means that the audio bitrate (in the case of an audio file) is stable and constant. In other words, if the bitrate is fixed at 320 kbps throughout the duration of the music, then it is definitely CBR.
However, VBR (Variable Bit Rate) is much more commonly used, especially for MP3s. The average bitrate in this case is around 256 kbps, but the bitrate can vary between 8 and 320 kbps.

Re-hello!
Thank you very much for your responses!
Actually, I need to upload texts on Deezer, and they only allow certain types of files.
I’m copying and pasting below:
"You must import one of these 3 formats:
- WAVE, in 16-bit, 44100Hz, and Stereo only,
- WINDOWS MEDIA, in 'lossless' format only,
- MP3, at 320 kbps and CBR format only.
Please make sure to use only one of these 3 formats.
Other audio formats are not allowed."
Formulated this way, it implied that there could be both 320 CBR and non-CBR.
I used Audacity (new to this type of software) to encode my texts, and they are indeed in 320, but I can't find any reference to CBR (in preferences or help), so I had some doubts.
All I find is the bitrate to choose in "preferences" then "MP3 export settings," with the version of the mp3 library (lame v3.97)

Hello,
If you are not sure about anything, you have several free tools to check or encode in the format you desire:
- MediaInfo (free+open source) allows you to know the characteristics of the audio and/or video file. Additionally, it can be integrated into the context menu.
- MediaCoder (proprietary+free) is a universal audio/video encoding/transcoding software.
You can keep Audacity for audio editing and manipulation (cutting, adding effects, fades, etc.). As for the manipulation of the encoding of an audio/video file, I recommend using MediaCoder, a true gem in its field.
Once you have started it:
- at the top part, [ADD] your audio file (wav, mp3, aac...) to the work list.
- in the bottom left part, you have the tabs Preview/Tasking/Video/Audio/.../Streaming
- in Video, uncheck Enabled
- in Audio, select MP3 (which is set by default), and below the Lame-MP3 encoder will be automatically selected/greyed out (if the Auto box is checked)
- in the bottom right part, you will have in the LAME MP3 tab: the CBR bitrate mode (by default), the bitrate slider set to 128 kbps (by default) which you will move to 320, the channels Auto (which you can leave or set to Stereo or Joint-Stereo). These settings are also predefined in the Insane setting (CBR/320).
Well, even without this help, you will see that it is really child's play.
