I have received the audio messages I ordered, but I can't hear them very well. Is this normal?
The sound quality depends on the file format requested. For example, it is normal that WAV format, 8khz, and 16bit audio play with reduced quality, but this is not cause for worry as it is still typical phone sound quality. Clearly, it is impossible to hear everything in high-fidelity over the phone! However, to demonstrate that the work we have delivered is perfect, we will also provide a version in MP3, the highest quality.
