ACX AUDITION
Also Known as ACX Test Clip and ACX Sample.
An Audition is a short reading you can submit to ACX to prove your performance quality before you submit a whole book. ACX will review your work and post comments. The work does not have to be produced using Adobe Audition.
Works must be perfect and ‘Retail-Ready’. ACX will not change any work once you submit.
Auditions should be between three and five minutes long.
Auditions should have 0.5 to 1 second of Room Tone at the beginning and 1 to 5 seconds of Room Tone at the end.
Auditions must be in MP3 sound format with constant bitrate of 192, minimum.
Auditions must have sound peaks no louder than -3dB.
Auditions must have a voice RMS (loudness) value between -18dB and -23dB.
Auditions must have Room Tone (natural background room sound without you performing-or moving-or breathing) quieter than -60dB.
You can submit this audition to ACX after filling out a questionnaire.
