How can I provide the audio for my cassette production?
For the best quality you should provide your audio as 16bit 44.1kHz WAV files, ideally as complete A and B side single tracks as this can help to avoid any track order issues when we process the order, but if you do need to supply them as separate tracks then that is fine. If you do send separate tracks for each side then please clearly label them with the track order and which side they are on or supply them in separate folders for side A and B. The ideal numbering would be each track starting with A1, A2, A3…. B1, B2, B3…etc
If you are supplying merged A/B side masters, we would also recommend that you normalise the tracks to the same dBFS level to ensure a consistent recorded level across the tape.
When setting up audio for duplication we usually apply a high pass filter with a cut off at around 20 Hz so that the audio doesn’t trigger the cue tone on our bin loop system, we will do this automatically for you.
You should not worry too much about the digital level of submitted audio, as long as it is not clipping. This can easily be adjusted on the loop bin for optimal tape-recording level by our sound engineers. Usually, we start off with the audio normalised to -6 dBFS and then can increase or decrease it on the bin if necessary for the audio to peak at around 1-2 dB. If the supplied audio is overly compressed or extremely dynamic then it can also need tweaking slightly. A typical audio cassette has around 55 dB of dynamic range but in practice the usable dynamic range is lower than this.
You can also supply us with MP3 files if you prefer and whilst the quality of MP3s is not quite the same as a WAV file as MP3s are always compressed to some extent, it is unlikely to be noticeable in cassette duplication if supplying us with higher quality MP3s.
We don’t recommend sending AIFF or FLAC files as they as they are more prone to errors in our experience.
