1. A method, comprising: receiving an encoded frame that includes audio data; determining quantizer resolution data in response to information extracted from the encoded frame, the quantizer resolution data corresponding to a number of quantization intervals used during a process of quantizing mantissa values of transform coefficients for the audio data of the encoded frame; determining exponent profile data of transform coefficients from the encoded frame; determining a plurality of dequantization methods for the mantissa values of the encoded frame based, at least in part, on the quantizer resolution data and the exponent profile data; and dequantizing the mantissa values according to the dequantization methods.
