 ### After the session
 
-Modern recording studios run on computers. At the end of the session, you receive one or more audio files, not a tape. These files are probably WAV or AIFF format in CD quality (44.1 KHz 16-bit) or better. 24 KHz 16-bit is common and desirable. The default sampling rate for a custom neural voice is 24 KHz.  It's recommended that you should use a sample rate of 24 KHz for your training data. Higher sampling rates, such as 96 KHz, aren't usually needed.

 Speech Studio requires each provided utterance to be in its own file. Each audio file delivered by the studio contains multiple utterances. So the primary post-production task is to split up the recordings and prepare them for submission. The recording engineer might have placed markers in the file (or provided a separate cue sheet) to indicate where each utterance starts.
 
 Use your notes to find the exact takes you want, and then use a sound editing utility, such as [Avid Pro Tools](https://www.avid.com/en/pro-tools), [Adobe Audition](https://www.adobe.com/products/audition.html), or the free [Audacity](https://www.audacityteam.org/), to copy each utterance into a new file.
 
 Listen to each file carefully. At this stage, you can edit out small unwanted sounds that you missed during recording, like a slight lip smack before a line, but be careful not to remove any actual speech. If you can't fix a file, remove it from your dataset and note that you've done so.
 
-Convert each file to 16 bits and a sample rate of 24 KHz before saving and if you recorded the studio chatter, remove the second channel. Save each file in WAV format, naming the files with the utterance number from your script.

 Finally, create the transcript that associates each WAV file with a text version of the corresponding utterance. [Train your voice model](./professional-voice-train-voice.md) includes details of the required format. You can copy the text directly from your script. Then create a Zip file of the WAV files and the text transcript.
