Be careful not to make the file size too large

Please note that Mr. Transcription only allows you to upload files up to 1GB in size.

A WAV file will be about 600MB (about 0.6GB) per hour, so if you are recording for a long time, it is recommended that you divide it into parts when recording, or use a tool to split the file later .

3. Pay attention to recording quality

Pay attention to the quality of the recording

If your microphone is poor quality or there is room noise, the good sound quality of your WAV file will be meaningless.

We recommend using an external microphone or adjusting the location of the microphone to ensure you record with the best possible sound quality .

*However, because Transcription-san is a highly functional program, it can transcribe with high accuracy even if there is some noise.
