| Summary | 0018570: Audio is distorted for some loud IEEE float WAV files | ||||
| Description | User sent us WAV files with loud sound in PCM IEEE float format, which are played distorted in MM, but not in other apps. After conversion to other formats (in external application), including standard PCM with 24 bit integer, it plays correctly. | ||||

Verified 2522 Tested on up to 64Bit floating point precision. Testing cases https://en.wikipedia.org/wiki/Audio_bit_depth#Quantization and files are saved from fe of these apps https://en.wikipedia.org/wiki/Audio_bit_depth#Applications |
